The way this works is that 'is_locked' gets the value of the plock->lock and plock->lock gets the value of
'is_locked' which we just set to 'true'. Basically this is an atomic 'swap' command. If the lock had not yet been
reserved then its value would be 'false' and after the xchg() instruction finished 'is_locked' would have
'false'. If it had already been reserved then 'is_locked' would have 'true' after the xchg() instruction. Since
plock->lock was already 'true' and we just set it back to 'true' everything is ok. To see if we reserved the lock
we just need to check the value of 'is_locked' after this instruction finishes. */

* The following steps are taken in the startup code:
* 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.
* Arguments : none
* Return value : none

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.

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.

PLEASE REFER TO THE APPLICATION NOTE FOR THIS MIDDLEWARE FOR MORE INFORMATION
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
