void __ARMLIB_isrEnableIRQ(void);
__ARMLIB_isrEnableIRQ re-enables the ARM's global interrupts from within an ISR enabling reentrant IRQ interrupt handlers.
Calls to __ARMLIB_isrEnableIRQ should be accompanied with a call to __ARMLIB_isrDisableIRQ prior to completion of the ISR.
__ARMLIB_isrEnableIRQ is an ARM specific extension provided by CrossWorks C.
