IRQ
ACK1 — IRQ1 Interrupt Request Acknowledge Bit
Writing a logic 1 to this write-only bit clears the IRQ1 CPU interrupt
request. ACK1 always reads as logic 0. Reset clears ACK1.
IMASK1 — IRQ1 Interrupt Mask Bit
Writing a logic 1 to this read/write bit disables IRQ1 CPU interrupt
requests. Reset clears IMASK1.
1 = IRQ1 CPU interrupt requests masked
0 = IRQ1 CPU interrupt requests not masked
MODE1 — IRQ1 Pin Edge/Level Select Bit
This read/write bit controls the triggering sensitivity of the IRQ1 pin.
Reset clears MODE1.
1 = IRQ1 CPU interrupt requests on falling edges and low levels
0 = IRQ1 CPU interrupt requests on falling edges only
