1 The PDSR and PSSR registers are described in Chapter 14, “General Purpose I/O Module. All programmable signals default to 2mA drive in normal

(single-chip) mode.

2 All signals have a pull-up in GPIO mode.

3 The use of an external PHY limits ADC, interrupt, and QSPI functionality. It also disables the UART0/1 and timer pins.

4 The multiplexed CANTX and CANRX signals do not have dedicated pins, but are available as muxed replacements for other signals.

5 The VDD1, VDD2, VDDPLL, and PHY_VDD pins are for decoupling only and should not have power directly applied to them.

6 For primary and GPIO functions only.

7 Only when JTAG mode is enabled.

8 For secondary and GPIO functions only.

9 RSTI has an internal pull-up resistor; however, the use of an external resistor is strongly recommended.

10 For GPIO function. Primary Function has pull-up control within the GPT module.

11 This list for power and ground does not include those dedicated power/ground pins included elsewhere, e.g. in the Ethernet PHY.
