These signals are multiplexed on other pins.
For primary and GPIO functions only.
Only when JTAG mode is enabled.
CLKMOD0 and CLKMOD1 have internal pull-down resistors; however, the use of external resistors is very strongly recommended.
When these pins are configured for USB signals, they should use the USB transceiver’s internal pull-up/pull-down resistors (see the description of the
OTG_CTRL register). If these pins are not configured for USB signals, each pin should be pulled down externally using a 10 kΩ resistor.
For secondary and GPIO functions only.
RSTI has an internal pull-up resistor; however, the use of an external resistor is very strongly recommended.
For GPIO function. Primary Function has pull-up control within the GPT module.
