ENTRFIRQ firq_handler:
The ENTRFIRQ directive causes the assembler to flag the first four to five instructions in a firq service routine, in which certain instructions are not allowed. The assembler processes these flagged instructions before the first instruction of a faster interrupt handler.
The core reference manual contains information on Fast Interrupt Processing.
This directive applies to the DSP56800E processor.
