h. Ports
Input port (Port 0.0 to Port 0.3):
Selectable as input with pull-up resistor/high-impedance input
Provided with the reset function that resets the system when there is a simultaneous key
depression of multiple bits (2, 3, or 4 bits).
Output port: Selectable as N-channel open drain output/CMOS output
Enabled only when the SEG pins (L32 to L35) are selected as the output port by the mask
option.
Input-output port (Port A.0 to Port A.3, Port B.0 to Port B.3, Port C.0 to Port C.3, Port E.0 to Port E.3):
Selectable as input with pull-up resistor/input with pull-down resistor/high-impedance input
Selectable as P-channel open drain output/N-channel open drain output/CMOS output/high-
impedance output
