Port 00~03 : The Port characteristic is specified by the software and the use of pull-up resistors for each port is specified by the option SW.
Port 10~13 : The Port characteristic and the use of pull- up resistors for each port is specified by the software.
* The Port characteristic means I/O characteristic and Port description - CMOS or N-channel open drain needed pull-up resistors.
Teriminal I/O Pull- up resistor status at selection pull-up option.
Port 0 I Pull- up resistor OFF, ON after reset release.
Port 1 I Programmable pull- resistor OFF.
