1
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
normal (single-chip) mode.
2 All signals have a pull-up in GPIO mode.
3 These signals are multiplexed on other pins.
4
For primary and GPIO functions only.
5
Only when JTAG mode is enabled.
6
CLKMOD0 and CLKMOD1 have internal pull-down resistors; however, the use of external resistors is very strongly recommended.
7
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 k
Ω resistor.
8 For secondary and GPIO functions only.
9
RSTI has an internal pull-up resistor; however, the use of an external resistor is very strongly recommended.
10
For GPIO function. Primary Function has pull-up control within the GPT module.
