to
P0.31
I/O
Port 0: Port 0 is a 32-bit bi-directional I/O port with individual direction controls for each bit. The
operation of port 0 pins depends upon the pin function selected via the Pin Connect Block.
Pins 26 and 31 of port 0 are not available.
Note: All Port 0 pins excluding those that can be used as A/D inputs (P0.27, P0.28, P0.29 and
P0.30) are functionally 5V tolerant. If the A/D converter is not used at all, pins associated with A/
D inputs can be used as 5V tolerant digital IO pins. See "A/D Converter" chapter for A/D input pin
voltage considerations.
