IDT 79RC32351
Table 14 shows the pin numbering for the Standard EJTAG connector. All the even numbered pins are connected to ground. Multiplexing of pin
functions should be considered when connecting
EJTAG_TRST_N and EJTAG_PCST.
For details on using the JTAG connector, see the JTAG chapters in the RC32351 user reference manual.

1.
The value of the series resistor may depend on the actual printed circuit board layout situation.
2.
JTAG_TCK pull-up resistor is not required according to the JTAG (IEEE1149) standard. It is indicated here to prevent a floating CMOS input when the EJTAG connector is
unconnected.

EJTAG_TRST_N
Input
10 k
pull-down resistor. A pull-down resistor will hold the EJTAG controller in reset when not in use
if the EJTAG_TRST_N function is selected with the boot configuration vector. Refer to the User Man-
ual.
