The value of the series resistor may depend on the actual printed circuit board layout situation.
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

An equivalent load of 50 pF is derived from the tester load plus an
10 kΩ pull-up resistor
10 kΩ pull-up resistor
10 kΩ pull-up resistor is used if it is combined with the system cold reset control, COLDRSTN.
This can be connected to the boot configuration vector to control debug boot mode if desired. Refer
Used to sense the circuit board power. Must be connected to the VCC I/O supply of the circuit board.
10 kΩ 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-
