The on-chip voltage regulator enable pin (ENVREG)
must always be connected directly to a supply voltage.
Refer to Section 26.2 “On-Chip Voltage Regulator”
for details on connecting and using the on-chip
regulator.
When the regulator is enabled, a low-ESR (<5Ω)
capacitor is required on the V
voltage regulator output voltage. The V
be connected to V
connected to ground. The type can be ceramic or
tantalum.

The PGECx and PGEDx pins are used for In-Circuit
Serial Programming™ (ICSP™) and debugging pur-
poses. 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 recommended, 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
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communi-
cations to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin input voltage high
(V
For device emulation, ensure that the “Communication
Channel Select” (i.e., PGECx/PGEDx pins) programmed
into the device matches the physical connections for the
ICSP to the Microchip debugger/emulator tool.
For
development tools connection requirements, refer to
Section 27.0 “Development Support”.
