The only require- ment for exit is that an interval, P16, should elapse between the last clock and program signals on PGCx and PGDx before removing VIH. FIGURE 4-6: EXITING ENHANCED ICSP™ MODE Send PROGW Command ConfigAddress = 0157FCh(1) Is PROGW response PASS? No Yes No Failure Report Error Start Finish Yes Is ConfigAddress 0157FEh?(1) ConfigAddress = ConfigAddress + 2 Note 1: Configuration Word addresses for PIC24FJ128GA devices are shown.
