4.2
Another possible interface is the 2-wire ICSP port.
Table 4-2 lists the required pin connections. This inter-
face uses the following 2 communication lines to trans-
fer data to and from the PIC32MX device being
programmed:
• PGCx – Serial Program Clock
• PGDx – Serial Program Data
These signals are described in the following two
sections. Refer to the specific device data sheet for the
connection of the signals to the chip pins.
4.2.1
PGCx is the clock that controls the updating of the TAP
controller and the shifting of data through the Instruc-
tion or selected Data register(s). PGCx is independent
of the processor clock, with respect to both frequency
and phase.
4.2.2
PGDx is the data input/output to the Instruction or
selected Data Register(s), it is also the control signal
for the TAP controller. This signal is sampled on the
falling edge of PGC for some TAP controller states.
4.3
All devices in the PIC32MX family are dual voltage
supply designs: one supply for the core and peripherals
and another for the I/O pins. Some devices contain an
on-chip regulator to eliminate the need for two external
voltage supplies.
All of the PIC32MX devices power their core digital
logic at a nominal 1.8V. This may create an issue for
designs that are required to operate at a higher typical
voltage, such as 3.3V. To simplify system design, all
devices in the PIC32MX family incorporate an on-chip
regulator that allows the device to run its core logic from
