5 Port0 – Port 5
Port 0 ~ Port 5 are the general purpose IO of this controller. Most of the ports are multiplexed with
the other outputs, e.g., Port 3[0] is also used as RXD in the UART application. Port0 is open-drain in
the input and output high condition; so external pull-up resistors are required. As for the other ports,
the pull-up resistors are built internally.
For general-purpose applications, every pin can be assigned to either high or low independently as
given below:
