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 100 Ohms.
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
Ensure that the “Communication Channel Select” (i.e.,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to

The TMS, TDO, TDI and TCK pins are used for testing
and debugging according to the Joint Test Action
Group (JTAG) standard. It is recommended to keep the
trace length between the JTAG connector and the
JTAG pins on the device as short as possible. If the
JTAG 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 100
Ohms.
Pull-up resistors, series diodes and capacitors on the
TMS, TDO, TDI and TCK pins are not recommended
as they will interfere with the programmer/debugger

nents are an application requirement, they should be
