5.1 Port P0 (P00 to P02)

Port P0 is a 3-bit input/output port that can also be used for external interrupt input or PPG output.

A reset initializes the output latch (P0DR) to “1” and the Pch control (P0OUTCR) to “0”.

To use a pin in Port P0 as an input port or external interrupt input, set P0DR to “1” and then set the corresponding

bit in P0OUTCR to “0”.

To use a pin in Port P0 as a PPG output, set P0DR to “1”.

The output circuit of Port P0 can be set either as sink open-drain output (“0”) or CMOS output (“1”) individually

for each bit in P0OUTCR.

Port P0 has a separate data input register. The output latch state can be read from the P0DR register, and the pin

state can be read from the P0PRD register.
