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.
