FUNCTION

ACC ← P00 - P03, with pull-up resistor

I/O selectable by instructions, with pull-up resistor

I/O selectable independently, with pull-up resistor. Sound output only when P23 pin is used

as an output

Serial interface I/O by setting the mode register RE, with pull-up resistor

Selectable between segment ports and I/O ports through an RC register

Display RAM contents output as LCD segment signals

4-value output capability; used for LCD common output

For test (connected to GND normally), with pull-down resistor

Auto clear, with pull-up resistor
