Note 1: INTF flag is sampled here (every Q1).
2: Asynchronous interrupt latency = 3-5 TCY. Synchronous latency = 3-4 TCY, where TCY = instruction cycle time.
Latency is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
3: CLKOUT not available in all Oscillator modes.
4: For minimum width of INT pulse, refer to AC specifications in Section 30.0 “Electrical Specifications””.
5: INTF is enabled to be set any time during the Q4-Q1 cycles.
