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
