External Interrupt (IRQ)
Advance Information
218
IRQF1 — IRQ1 Flag
ACK1 — IRQ1 Interrupt Request Acknowledge Bit
IMASK1 — IRQ1 Interrupt Mask Bit
MODE1 — IRQ1 Edge/Level Select Bit
This read-only status bit is high when the IRQ1 interrupt is pending.
Writing a logic one to this write-only bit clears the IRQ1 latch. ACK1
always reads as logic zero. Reset clears ACK1.
Writing a logic one to this read/write bit disables IRQ1 interrupt
requests. Reset clears IMASK1.
This read/write bit controls the triggering sensitivity of the IRQ1/V
pin. Reset clears MODE1.
1 = IRQ1 interrupt pending
0 = IRQ1 interrupt not pending
1 = IRQ1 interrupt requests disabled
0 = IRQ1 interrupt requests enabled
1 = IRQ1/V
0 = IRQ1/V
