Port 0 ~ Port 4 are the general purpose IO of this controller. Port 4[3:0] is available with 44-pin
PLCC or QFP package only, not for 40-pin package. 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
because their SFRs are bit addressable as given below：
