IDLE Mode Timing Requirements MIN NOM MAX UNIT Without input qualifier 2tc(SCO) tw(WAKE-INT) Pulse duration, external wake-up signal cycles With input qualifier 1tc(SCO) + IQT (1) (1) Input Qualification Time (IQT) = [tc(SCO) × 2 × QUALPRD] × 5 + [tc(SCO) × 2 × QUALPRD]. Table 6-13. IDLE Mode Switching Characteristics PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Delay time, external wake signal to program execution resume(1) Without input qualifier 8tc(SCO) • Wake-up from Flash cycles – Flash module in active state With input qualifier 8tc(SCO) + IQT (2) td(WAKE-IDLE) Without input qualifier 1050tc(SCO) • Wake-up from Flash cycles – Flash module in sleep state With input qualifier 1050tc(SCO) + IQT (2) Without input qualifier 8tc(SCO) • Wake-up from SARAM cycles With input qualifier 8tc(SCO) + IQT (2) (1) This is the time taken to begin execution of the instruction that immediately follows the IDLE instruction. Execution of an ISR (triggered by the wake-up) signal involves additional latency. (2) Input Qualification Time (IQT) = [tc(SCO) × 2 × QUALPRD] × 5 + [tc(SCO) × 2 × QUALPRD]. A. XCLKOUT = SYSCLKOUT B. WAKE INT can be any enabled interrupt, WDINT, XNMI, or XRS. Figure 6-15.
