11.1
Introduction
Table 11.1 lists Programmable I/O Port Specifications (hereafter referred to as I/O ports).
Each pin functions as a programmable I/O port or a peripheral function input/output.
To set peripheral functions, refer to the description for the individual function. To use ports as peripheral
function input/output pins, refer to 11.4 "Peripheral Function I/O".
Table 11.2 lists the I/O ports.
