Enable critical section calls in the the called function.
OS_PORT_CRITICAL_ENABLE() will be called at the beginning of any function that uses OS_CRITICAL_BEGIN or OS_CRITICAL_END. This will be the first call after variable declaration. This is a good place to define variables that may be used by OS_BEGIN_CRITICAL and OS_CRITICAL_END

| #define OS_PORT_CRITICAL_BEGIN | ( | ) |
Begin a critical section A simple way to do this would be to disable interrupts.
However, it would be better if the current interrupt state were stored and then interrupts were disabled. Upon ending the critical section, the stored state should be restored. The stored state can be saved in a local variable, which can be defined within OS_PORT_CRITICAL_ENABLE()

| #define OS_PORT_CRITICAL_END | ( | ) |
End a critical section This may be as simple as reenabling interrupts, but it is better to renable the interrupt state stored in OS_PORT_BEGIN_CRITICAL().

Value:
extern uint8_t os_isr_nesting; \ os_isr_nesting++;
Leave this as such
