IRQ1F — IRQ1 Flag Bit
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 1 to this write-only bit clears the IRQ1 latch. ACK1
always reads as logic 0. Reset clears ACK1.
Writing a logic 1 to this read/write bit disables IRQ1 interrupt requests.
Reset clears IMASK1.
This read/write bit controls the triggering sensitivity of the IRQ pin.
Reset clears MODE1.
