FIGURE 4-5: CONFIGURATION BIT PROGRAMMING FLOW

4.7 Exiting Enhanced ICSP Mode

Exiting Program/Verify mode is done by removing VIH

from MCLR, as shown in Figure 4-6. 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 V

IH.
