External Interrupt (IRQ)
Data Sheet
342
IRQ2F — IRQ2 Flag Bit
ACK2 — IRQ2 Interrupt Request Acknowledge Bit
IMASK2 — IRQ2 Interrupt Mask Bit
MODE2 — IRQ2 Edge/Level Select Bit
This read-only status bit is high when the IRQ2 interrupt is pending.
Writing a logic 1 to this write-only bit clears the IRQ2 latch. ACK2
always reads as logic 0. Reset clears ACK2.
Writing a logic 1 to this read/write bit disables IRQ2 interrupt requests.
Reset clears IMASK2.
This read/write bit controls the triggering sensitivity of the IRQ2 pin.
Reset clears MODE2.
1 = IRQ2 interrupt pending
0 = IRQ2 interrupt not pending
1 = IRQ2 interrupt requests disabled
0 = IRQ2 interrupt requests enabled
1 = IRQ2 interrupt requests on falling edges and low levels
0 = IRQ2 interrupt requests on falling edges only
