8.8 Registers
The IRQ status and control register (INTSCR) controls and monitors operation of the IRQ module. The
INTSCR:
IRQF — IRQ Flag Bit
ACK — IRQ Interrupt Request Acknowledge Bit
IMASK — IRQ Interrupt Mask Bit
MODE — IRQ Edge/Level Select Bit
Freescale Semiconductor

This read-only status bit is set when the IRQ interrupt is pending.
Writing a 1 to this write-only bit clears the IRQ latch. ACK always reads 0.
Writing a 1 to this read/write bit disables the IRQ interrupt request.
This read/write bit controls the triggering sensitivity of the IRQ pin.
1 = IRQ interrupt pending
0 = IRQ interrupt not pending
1 = IRQ interrupt request disabled
0 = IRQ interrupt request enabled
1 = IRQ interrupt request on falling edges and low levels
0 = IRQ interrupt request on falling edges only
Shows the state of the IRQ flag
Clears the IRQ latch
Masks the IRQ interrupt request
Controls triggering sensitivity of the IRQ interrupt pin
