6.3 INTRQ INTERRUPT REQUEST REGISTER
INTRQ is the interrupt request flag register. The register includes all interrupt request indication flags. Each one of the
interrupt requests occurs, the bit of the INTRQ register would be set “1”. The INTRQ value needs to be clear by
programming after detecting the flag. In the interrupt vector of program, users know the any interrupt requests
occurring by the register and do the routine corresponding of the interrupt request.
