1 The PDSR and PSSR registers are part of the GPIO module. All programmable signals default to 2mA drive in normal (single-chip) mode.
2 All signals have a pull-up in GPIO mode.
3 I2C1 is multiplexed with specific pins of the QSPI, UART1, UART2, and Mini-FlexBus pin groups.
4 For primary and GPIO functions only.
5 Only when JTAG mode is enabled.
6 For secondary and GPIO functions only.
7 RSTI has an internal pull-up resistor; however, the use of an external resistor is strongly recommended.
8 For GPIO functions, the Primary Function has pull-up control within the GPT module.
9 Available on 144-pin packages only.
10 This list for power and ground does not include those dedicated power/ground pins included elsewhere, such as in the ADC, USB, and PLL.
