Note
1:
INTF flag is sampled here (every Q1).
2:
Asynchronous interrupt latency = 3-4 TCY. Synchronous latency = 3 TCY, where TCY = instruction cycle time.
Latency is the same whether Inst (PC) is a single cycle or a 2-cycle instruction.
3:
CLKOUT is available only in INTOSC and RC Oscillator modes.
4:
For minimum width of INT pulse, refer to AC specifications in Section 15.0 “Electrical Specifications”.
5:
INTF is enabled to be set any time during the Q4-Q1 cycles.
