Type

Function

I/O 16-bit bidirectional I/O port, bit-wise programmable for input or output via direction

bit. Programming an I/O pin as input forces the corresponding output driver to high

impedance state. Port 2 outputs can be configured as push-pull or open drain

drivers. The input threshold of Port 2 is selectable (TTL or special).

The following Port 2 pins have alternate functions:

I/O P2.0 CC0IO

CAPCOM: CC0 Capture Input / Compare Output

I/O 15-bit (P3.14 is missing) bidirectional I/O port, bit-wise programmable for input or

I/O output via direction bit. Programming an I/O pin as input forces the corresponding

I/O output driver to high impedance state. Port 3 outputs can be configured as push-pull

or open drain drivers. The input threshold of Port 3 is selectable (TTL or special).
