(1)

I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal.

Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the the signal name

highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured

function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different

types (i.e., input versus output), the table reflects the pin function direction for that particular peripheral.

IPD = Internal Pulldown resistor, IPU = Internal Pullup resistor
