Pin Configuration
Type
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.
I/O
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.
