On the PIC18F66K80 family devices, the regulator is
enabled and a low-ESR (< 5Ω) capacitor is required on

When the regulator is disabled, a 0.1F capacitor
should be connected from the V
ground. This capacitor’s characteristics must be similar
to those of the “decoupling” capacitors explained in
Section 2.2.1. For details on the V

The PGC and PGD pins are used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes. It
is recommended to keep the trace length between the
ICSP connector and the ICSP pins on the device as
short as possible. If the ICSP connector is expected to
experience an ESD event, a series resistor is recom-
mended, with the value in the range of a few tens of
ohms, not to exceed 100Ω.
Pull-up resistors, series diodes, and capacitors on the
PGC and PGD pins are not recommended as they will
interfere with the programmer/debugger communica-
tions to the device. If such discrete components are an
application requirement, they should be removed from
the circuit during programming and debugging. Alter-
natively, refer to the AC/DC characteristics and timing
requirements information in the respective device

capacitive loading limits, and pin input voltage high

For device emulation, ensure that the “Communication
Channel Select” (i.e., PGCx/PGDx pins) programmed
into the device matches the physical connections for
the ICSP to the Microchip debugger/emulator tool.
