FIGURE 12-8: INT PIN INTERRUPT TIMING TABLE 12-6: SUMMARY OF REGISTERS ASSOCIATED WITH INTERRUPTS Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Value on POR, BOR Value on all other Resets INTCON GIE PEIE T0IE INTE GPIE T0IF INTF GPIF 0000 0000 0000 0000 IOC — — IOC5 IOC4 IOC3 IOC2 IOC1 IOC0 --00 0000 --00 0000 PIR1 EEIF ADIF CCP1IF — CMIF OSFIF TMR2IF TMR1IF 000- 0000 000- 0000 PIE1 EEIE ADIE CCP1IE — CMIE OSFIE TMR2IE TMR1IE 000- 0000 000- 0000 Legend: x = unknown, u = unchanged, – = unimplemented read as ‘0’, q = value depends upon condition. Shaded cells are not used by the interrupt module. Q2 Q1 Q3 Q4 Q2 Q1 Q3 Q4 Q2 Q1 Q3 Q4 Q2 Q1 Q3 Q4 Q2 Q1 Q3 Q4 OSC1 CLKOUT INT pin INTF flag (INTCON reg.) GIE bit (INTCON reg.) INSTRUCTION FLOW PC Instruction Fetched Instruction Executed Interrupt Latency PC PC + 1 PC + 1 0004h 0005h Inst (0004h) Inst (0005h) Dummy Cycle Inst (PC) Inst (PC + 1) Inst (PC – 1) Inst (0004h) Dummy Cycle Inst (PC) — 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.
