Note 1: INTF flag is sampled here (every Q1).

2: Asynchronous interrupt latency = 3-5 T

CY. 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: For minimum width of INT pulse, refer to AC specifications in Section 29.0 “Electrical Specifications”.

4: INTF is enabled to be set any time during the Q4-Q1 cycles.
