3. The TEST pin must be grounded and the IM2/1, IM0/ID, and OPOFF pins must be grounded or
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
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
8. The following shows the relationship between the operation frequency (fosc) and current
Iop ( A)
9. Each COM and SEG output voltage is within ±0.15 V of the LCD voltage (Vcc, V1, V2, V3, V4, V5)
10. Applies to the external clock input (figure 43).
