Section 14.11: In-Circuit Serial Programming and
Figure 14-18: Typical In-Circuit Serial Programming
Connection. The following paragraph and Note box
are being added to the end of Section 14.11 and
Figure 14-18 is updated to include PGM, noted in
bold.
14.11 In-Circuit Serial Programming
If LVP is not being used for programming, but the LVP
Configuration bit is set (or LVP feature is enabled), the
PGM pin must not be allowed to toggle while
programming. The PGM pin is edge sensitive and if an
edge is detected during programming, it may cause the
PC to reset. If the LVP feature is disabled, the PGM pin
will have no effect on programming.
