The PDSR and PSSR registers are described in the General Purpose I/O chapter. All programmable signals default to 2 mA drive and FAST slew rate in
All signals have a pull-up in GPIO mode.
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.
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.
