INTF flag is sampled here (every Q1).
Asynchronous interrupt latency = 3 – 4 T
Latency is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
CLKOUT is available only in INTOSC and RC Oscillator modes.
For minimum width of INT pulse, refer to AC specifications in Section 18.0 “Electrical Specifications”.
INTF is enabled to be set any time during the Q4 – Q1 cycles.
