* 1. The User Stack Pointer (USP) and Interrupt Stack Pointer (ISP) are both set immediately after entry
* to this function. The USP and ISP stack sizes are set in the file stacksct.h.
* Default sizes are USP=4K and ISP=1K.
* 2. The interrupt vector base register is set to point to the beginning of the relocatable interrupt
* vector table.
* 3. The MCU is setup for floating point operations by setting the initial value of the Floating Point
* Status Word (FPSW).
* 4. The MCU operating frequency is set by configuring the Clock Generation Circuit (CGC) in
* operating_frequency_set.
* 5. Calls are made to functions to setup the C runtime environment which involves initializing all
* initialed data, zeroing all uninitialized variables, and configuring STDIO if used
* (calls to _INITSCT and _INIT_IOLIB).
* 6. Board-specific hardware setup, including configuring I/O pins on the MCU, in hardware_setup.
* 7. Global interrupts are enabled by setting the I bit in the Program Status Word (PSW), and the stack
* is switched from the ISP to the USP. The initial Interrupt Priority Level is set to zero, enabling
* any interrupts with a priority greater than zero to be serviced.
* 8. The processor is optionally switched to user mode. To run in user mode, set the macro
* RUN_IN_USER_MODE above to a 1.
* 9. The bus error interrupt is enabled to catch any accesses to invalid or reserved areas of memory.
*
* Once this initialization is complete, the user's main() function is called. It should not return.

r_bsp Package
=============
Document Number
---------------
N/A
Version
-------
v1.60
Overview
--------
The r_bsp package provides a foundation for code to be built on top of. It provides startup code, iodefines, and MCU
information for different boards. There are 2 folders that make up the r_bsp package. The 'mcu' folder has iodefine
files and a file named 'mcu_info.h' for each MCU group. The 'mcu_info.h' file has information about the MCU on the board
and is configured based on the information given in r_bsp_config.h. The information in 'mcu_info.h' is used to help
configure Renesas middleware that uses the r_bsp package. The 'board' folder has a folder with startup code for each
supported board. Which MCU and board is chosen is decided by the settings in 'platform.h'. The user can choose which
board they are using by uncommenting the include path that applies to their board. For example, if you are using the
RSK+RX62N then you would uncomment the #include "./board/rskrx62n/r_bsp.h" include path. Users are encouraged to add
their own boards to the 'board' directory. BSPs are configured by using the r_bsp_config.h file. Each board will have a
reference configuration file named r_bsp_config_reference.h. The user should copy this file to their project, rename it
to r_bsp_config.h, and use the options inside the file to configure the BSP for their project.
Features
--------
* Provides foundation to build code on top of.
* Provides MCU startup code.
* Provides SFR access through iodefine.h
* Stores details of MCU in 'mcu_info.h' to help configure Renesas middleware.
* Easily configure BSP through r_bsp_config.h.
* Choose MCU easily by inputting part number details in r_bsp_config.h.
* Provides callbacks for MCU exceptions and the bus error interrupt.
Limitations

Required Packages
-----------------
* r_glyph [required if you want to use LCD for RDK boards]
* r_rspi_rx [required if you want to use LCD for RDK boards]
How to add to your project
--------------------------
* Copy the r_bsp folder to your project.
* Add an include path to the 'r_bsp' directory.
* Add all of the source files for your board from the 'r_bsp\board\--YOUR_BOARD--' directory to your project.
* Uncomment the include path for your board in 'platform.h' which is located in the 'r_bsp' directory.
* Copy the file r_bsp_config_reference.h from the 'r_bsp\board\--YOUR_BOARD--' directory and copy it to your project's
source code directory. Rename the file r_bsp_config.h.
* Open r_bsp_config.h and use the macros to configure the BSP for your project.

is that no extra processing is used for polling and the use of a system timer tick is not a requirement. The downside
of using interrupts is that callback functions are called from within an interrupt so if your ISR is long then it can
degrade the real-time response of your system. The benefit of polling is that functions are called at the application
level and debouncing is supported. The downside to polling is that your system must call the R_SWITCHES_Update() on a

Switches
========
Document Number
---------------
N/A
Version
-------
v1.40
Overview
--------
Configures port pins for switches and calls user defined function on switch press. Switch presses can be detected using
IRQ interrupts or by polling. The benefit of using interrupts is that no extra processing is used for polling and the
use of a system timer tick is not a requirement. The downside of using interrupts is that callback functions are called
from within an interrupt so if your ISR is long then it can degrade the real-time response of your system. The benefit
of polling is that functions are called at the application level and debouncing is supported. The downside to polling is
that your system must call the R_SWITCHES_Update() on a regular basis which requires extra processing.
Features
--------
* Call one function to setup switches.
* Define function to call when switch is pressed.
* Can be configured to be interrupt or poll driven.
Supported MCUs
--------------
* RX610 Group
* RX621, RX62N Group

/* ****************************************************************************
* This project includes a lot of tasks and tests and is therefore complex.
* If you would prefer a much simpler project to get started with then select
* the 'low power' demo by setting configCREATE_LOW_POWER_DEMO to 1 in
* FreeRTOSConfig.h. When configCREATE_LOW_POWER_DEMO is set to 1 main() will
* call main_low_power() instead of main_full().
* ****************************************************************************
*
* Creates all the demo application tasks, then starts the scheduler. The web
* documentation provides more details of the standard demo application tasks,
* which provide no particular functionality but do provide a good example of
* how to use the FreeRTOS API.
*
* In addition to the standard demo tasks, the following tasks and tests are
* defined and/or created within this file:
*
* "Reg test" tasks - These fill the registers with known values, then
* repeatedly check that each register still contains its expected value for
* the lifetime of the tasks. Each task uses different values. The tasks run
* with very low priority so get preempted very frequently. A check variable
* is incremented on each iteration of the test loop. A register containing an
* unexpected value is indicative of an error in the context switching
* mechanism and will result in a branch to a null loop - which in turn will
* prevent the check variable from incrementing any further and allow the check
* timer (described below) to determine that an error has occurred. The nature
* of the reg test tasks necessitates that they are written in assembly code.
*
* "Check Timer" and Callback Function - The check timer period is initially
* set to three seconds. The check timer callback function checks that all the
* standard demo tasks are not only still executing, but are executing without
* reporting any errors. If the check timer discovers that a task has either
* stalled, or reported an error, then it changes its own period from the
* initial three seconds, to just 200ms. The check timer callback function
* also toggles LED 0 each time it is called. This provides a visual
* indication of the system status: If the LED toggles every three seconds,
* then no issues have been discovered. If the LED toggles every 200ms, then
* an issue has been discovered with at least one task.
*
* *NOTE 1* The CPU must be in Supervisor mode when the scheduler is started.
* The PowerON_Reset_PC() supplied in resetprg.c with this demo has
* Change_PSW_PM_to_UserMode() commented out to ensure this is the case.

/* ****************************************************************************
* When configCREATE_LOW_POWER_DEMO is set to 1 in FreeRTOSConfig.h main() will
* call main_low_power(), which is defined in this file. main_low_power()
* demonstrates FreeRTOS tick suppression being used to allow the MCU to be
* placed into both the low power deep sleep mode and the low power software
* standby mode. When configCREATE_LOW_POWER_DEMO is set to 0 main will
* instead call main_full(), which is a more comprehensive RTOS demonstration.
* ****************************************************************************
*
* This application demonstrates the FreeRTOS tickless idle mode (tick
* suppression). See http://www.freertos.org/low-power-tickless-rtos.html
* The demo is configured to execute on the Renesas RX100 RSK.
*
* Functionality:
*
* + Two tasks are created, an Rx task and a Tx task.
*
* + The Rx task repeatedly blocks on a queue to wait for data. The Rx task
* toggles LED 0 each time is receives a value from the queue.
*
* + The Tx task repeatedly enters the Blocked state for an amount of time
* that is set by the position of the potentiometer. On exiting the blocked
* state the Tx task sends a value through the queue to the Rx task (causing
* the Rx task to exit the blocked state and toggle LED 0).
*
* If the value read from the potentiometer is less than or equal to
* mainSOFTWARE_STANDBY_DELAY then the Tx task blocks for the equivalent
* number of milliseconds. For example, if the sampled analog value is
* 2000, then the Tx task blocks for 2000ms. Blocking for a finite period
* allows the kernel to stop the tick interrupt and place the RX100 into
* deep sleep mode.
*
* If the value read form the potentiometer is greater than
* mainSOFTWARE_STANDBY_DELAY then the Tx task blocks on a semaphore with
* an infinite timeout. Blocking with an infinite timeout allows the kernel
* to stop the tick interrupt and place the RX100 into software standby
* mode. Pressing a button will generate an interrupt that causes the RX100
* to exit software standby mode. The interrupt service routine 'gives' the
* semaphore to unblock the Tx task.
*
*
* Using the Demo and Observed Behaviour:
*
* 1) Turn the potentiometer completely counter clockwise.
*
* 2) Program the RX100 with the application, then disconnect the programming/
* debugging hardware to ensure power readings are not effected by any
* connected interfaces.
*
* 3) Start the application running. LED 0 will toggle quickly because the
* potentiometer is turned to its lowest value. LED 1 will be illuminated
* when the RX100 is not in a power saving mode, but will appear to be off
* because most execution time is spent in a sleep mode. Led 2 will be
* illuminated when the RX100 is in deep sleep mode, and will appear to be
* always on, again because most execution time is spent in deep sleep mode.
* The LEDs are turned on and off by the application defined pre and post
* sleep macros (see the definitions of configPRE_SLEEP_PROCESSING() and
* configPOST_SLEEP_PROCESSING() in FreeRTOSConfig.h).
*
* 4) Slowly turn the potentiometer in the clockwise direction. This will
* increase the value read from the potentiometer, which will increase the
* time the Tx task spends in the Blocked state, which will therefore
* decrease the frequency at which the Tx task sends data to the queue (and
* the rate at which LED 0 is toggled).
*
* 5) Keep turning the potentiometer in the clockwise direction. Eventually
* the value read from the potentiometer will go above
* mainSOFTWARE_STANDBY_DELAY, causing the Tx task to block on the semaphore
* with an infinite timeout. LED 0 will stop toggling because the Tx task is
* no longer sending to the queue. LED 1 and LED 2 will both be off because
* the RX100 is neither running or in deep sleep mode (it is in software
* standby mode).
*
* 6) Turn the potentiometer counter clockwise again to ensure its value goes
* back below mainSOFTWARE_STANDBY_DELAY.
*
* 7) Press any of the three buttons to generate an interrupt. The interrupt
* will take the RX100 out of software standby mode, and the interrupt
* service routine will unblock the Tx task by 'giving' the semaphore. LED 0
* will then start to toggle again.
