Legend:
Note:
TTL = TTL input buffer
ANA = Analog level input/output
ST = Schmitt Trigger input buffer
I²C™ = I²C/SMBus input buffer
In some cases, I/O pins are multiplexed with more than one peripheral. In general, the dominant output control of a
multiplexed I/O pin can be determined by the order of the peripheral output names assigned to a pin (read from left to
right). Multiplexed peripheral inputs have no priority.
