* Method #1:  Disable/Enable interrupts using simple instructions.  After critical section, interrupts
*             will be enabled even if they were disabled before entering the critical section.  You MUST
*             change the constant in OS_CPU_A.ASM, function OSIntCtxSw() from 10 to 8.
*
* Method #2:  Disable/Enable interrupts by preserving the state of interrupts.  In other words, if 
*             interrupts were disabled before entering the critical section, they will be disabled when
*             leaving the critical section.  You MUST change the constant in OS_CPU_A.ASM, function 
*             OSIntCtxSw() from 8 to 10.
