The A/D module interrupt is implemented on the PIC16C924 only.
PC
2: Interrupt latency = 3-4 T
3: CLKOUT is available only in RC oscillator mode.
4: For minimum width of INT pulse, refer to AC specs.
5: INTF can be set anytime during the Q4-Q1 cycles.
Latency is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
