(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 (ie., input versus output), the table reflects the pin function direction for
that particular peripheral.
(2) IPD = Internal Pulldown resistor, IPU = Internal Pullup resistor
