data

(1)

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

Note: For multiplexed pins where functions have different types (i.e., input versus output), the table reflects the pin function direction for

that particular peripheral.

(2)

IPD = Internal Pulldown resistor, IPU = Internal Pullup resistor
