Pin Group
The PDSR and PSSR registers are part of the GPIO module. All programmable signals default to 2mA drive in normal (single-chip) mode.
All signals have a pull-up in GPIO mode.
I
For primary and GPIO functions only.
Only when JTAG mode is enabled.
For secondary and GPIO functions only.
RSTI has an internal pull-up resistor; however, the use of an external resistor is strongly recommended.
For GPIO functions, the Primary Function has pull-up control within the GPT module.
Available on 144-pin packages only.
This list for power and ground does not include those dedicated power/ground pins included elsewhere, such as in the ADC, USB, and PLL.
