/* Most ports implement critical sections by placing the interrupt flags on
the stack before disabling interrupts. Exiting the critical section is then
simply a case of popping the flags from the stack. As 78K0 IAR does not use
a frame pointer this cannot be done as modifying the stack will clobber all
the stack variables. Instead each task maintains a count of the critical
section nesting depth. Each time a critical section is entered the count is
incremented. Each time a critical section is left the count is decremented -
with interrupts only being re-enabled if the count is zero.
