1. S: supply; I: input; O: output; I/O: input/output
2. When used as an analog input, the signal goes to all analog modules, but the glitch during ADC sampling on this pin may
interfere with other analog inputs shared on this pin.

7.4.3 Pinout

The following figures show the pinout diagrams for the devices supported by this
document. Many signals may be multiplexed onto a single pin. To determine what signals
can be used on which pin, see
