Input pins used to acquire input data to RAM.
Output pins used to output RAM data.
Pull-down resistors are built in.
SO1 to SO3 are also used as the serial interface pins.
The serial interface function can be selected under program
control.
Pin functions:
SO1: Serial input
SO2: Serial output
SO3: Serial clock
The serial clock can be taken from either internal or external
sources, and can be set up to detect either rising or falling
edges under program control.

Input
IC internal reset input
The program counter is set to point to location 00H.
The reset input level can be set to be either high or low.
Either a pull-up or a pull-down resistor is built in.
Note: Applications must apply the reset signal level for at least
500 μs to effect a reset.

One of items (1) through (5) is selected as a mask option.
General-purpose output ports
(1) CMOS output
(2) p-channel open-drain output
(3) n-channel open-drain output
One of items (1) through (3) is selected as a mask option.
The adoption of the segment PLA in these microcontrollers
means that there is no need for programs to control the
LCD/general-purpose output states of these pins.
Output latch control is supported in the oscillator stopped
standby states and during a reset.
Any combination of LCD and general-purpose output functions
may be used.

Note: When a
combination of LCD drive
and general-purpose
outputs is selected, these
pins will be either:
All lit/high-level output, or
All off/low-level output.
During the reset period,
the LCD drive functions
as static drive.
