/LCD segment output
Output ports. Pins OT1 to OT20 can
be incremented by software, allowing
easy data access to external
RAM/ROM.
Can be set to LCD driver output by
software.
At 1/4 duty, controller can display up
to 136 segments using a matrix
consisting of COM1 to 4 and SEG1 to
34.
At 1/3 duty, can display up to 105
segments using a matrix consisting of
COM1 to 3 and SEG1 to 35.
At 1/2 duty, can display up to 72
segments using a matrix consisting of
COM1 to 2 and SEG1 to 36.
Set to output ports after a system
reset or clock stop.

/LCD segment output
4-bit CMOS I/O ports.
Input and output can be programmed
in 1-bit units.
These can be set bit by bit to LCD
driver output by software.
After a system reset, set to I/O port
input.
When a clock stop is executed, the
pins used as the LCD driver must be
set to output Low level (function as an
I/O port).

RESET
Reset input
Device’s system reset signal input pin.
Setting
RESET
to Low level triggers
a reset. When the pin is set to High,
the program starts from address 0.
Since system reset will start if the
voltage beyond 0 V to 3.5 V is
supplied to V

pin, this pin is used
by fixed to “H” level.
