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.
