External Interrupt (IRQ)
Technical Data
170
Address:
IRQF1 — IRQ1 Flag
ACK1 — IRQ1 Interrupt Request Acknowledge Bit
IMASK1 — IRQ1 Interrupt Mask Bit
MODE1 — IRQ1 Edge/Level Select Bit
IRQPUD — IRQ1 Pin Pull-up control bit
Reset:
Read:
Write:
POR:
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 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 interrupt requests on falling edges and low levels
0 = IRQ1 interrupt requests on falling edges only
1 = Internal pull-up is disconnected
0 = Internal pull-up is connected between IRQ1 pin and V
