PIC32MX
4.0
The PIC32MX family provides two possible physical
interfaces for connecting to and programming the
memory contents (Figure 4-1). For all programming
interfaces, the target device must be properly powered
and all required signals must be connected.
FIGURE 4-1:
4.1
One possible interface is the 4-wire JTAG (IEEE
1149.1) port. Table 4-1 lists the required pin connec-
tions. This interface uses the following four communi-
cation lines to transfer data to and from the PIC32MX
device being programmed:
• TCK – Test Clock Input
• TMS – Test Mode Select Input
• TDI – Test Data Input
• TDO – Test Data Output

These signals are described in the following four sec-
tions. Refer to the specific device data sheet for the
connection of the signals to the chip pins.
4.1.1
TCK 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). TCK is independent of
the processor clock with respect to both frequency and
phase.
4.1.2
TMS is the control signal for the TAP controller. This
signal is sampled on the rising edge of TCK.
4.1.3
TDI is the test data input to the Instruction or selected
Data register(s). This signal is sampled on the rising
edge of TCK for some TAP controller states.
4.1.4
TDO is the test data output from the Instruction or Data
register(s). This signal changes on the falling edge of
TCK. TDO is only driven when data is shifted out,
otherwise the TDO is tri-stated.
