DB4 to DB7
I/O
MPU
Four high order bidirectional tristate data bus pins. Used for
data transfer between the MPU and the HD66710. DB7 can
be used as a busy flag.
DB0 to DB3
I/O
MPU
Four low order bidirectional tristate data bus pins. Used for
data transfer between the MPU and the HD66710. These
pins are not used during 4-bit operation.
COM1 to COM33
O
LCD
Common signals; those are not used become non-selected
waveforms. At 1/17 duty rate, COM1 to COM16 are used for
character display, COM17 for icon display, and COM18 to
COM33 become non-selected waveforms. At 1/33 duty rate,
COM1 to COM32 are used for character display, and
COM33 for icon display.
SEG1 to SEG35

LCD
Segment signals
SEG36
O
LCD
Segment signal. When EXT = high, the same data as that of
the first dot of the extension driver is output.
SEG37/CL1
O
LCD/
Extension driver
Segment signal when EXT = low. When EXT = high, outputs
the extension driver latch pulse.
SEG38/CL2
O
LCD/
Extension driver
Segment signal when EXT = low. When EXT = high, outputs
the extension driver shift clock.
SEG39/D
O
LCD/
Extension driver
Segment signal at EXT = low. At EXT = high, the extension
driver data. Data on and after the 36th dot is output.
SEG40/M
O
LCD/
Extension driver
Segment signal when EXT = low. When EXT = high, outputs
the extension driver AC signal.
EXT

Extension driver enable signal. When EXT = high, SEG37 to
SEG40 become extension driver interface signals. At this
time, make sure that V5 level is lower than GND level (0 V).
V5 (low)
