2: Interrupt latency = 3-4 Tcy where Tcy = instruction cycle time.
3: CLKOUT is available only in RC oscillator mode.
4: For minimum width of INT pulse, refer to AC specs.
5: INTF is enabled to be set anytime during the Q4-Q1 cycles.
Latency is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
