Output form and existence of pull- up resistor for every port can be specified for each bit.
At port 1, Programable pull- up resistor provided when specifing either COOS or N- ch open drain output.
Port status in reset.
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.
