3. The TEST pin must be grounded and the IM2/1, IM0/ID, and OPOFF pins must be grounded or
connected to Vcc.
4. Corresponds to the high output for clock-synchronized serial interface.
5. Applies to the resistor value (RCOM) between power supply pins V1OUT, V2OUT, V5OUT, GND
and common signal pins, and resistor value (RSEG) between power supply pins V1OUT, V3OUT,
V4OUT, GND and segment signal pins, when current Id is flown through all driver output pins.
6. This excludes the current flowing through pull-up MOSs and output drive MOSs.
7. This excludes the current flowing through the input/output units. The input level must be fixed high
or low because through current increases if the CMOS input is left floating.
8. The following shows the relationship between the operation frequency (fosc) and current
consumption (Icc) (figure 42).

9. Each COM and SEG output voltage is within ±0.15 V of the LCD voltage (Vcc, V1, V2, V3, V4, V5)
when there is no load.
