6. The TEST pin must be grounded and the IM2/1, IM0/ID, and OPOFF pins must be grounded or
connected to Vcc.
7. Corresponds to the high output for clock-synchronized serial interface.
8. Applies to the resistor value (RCOM) between power supply pins V1OUT, V2OUT, V5OUT, GND and
common signal pins (COM1 to COM24, COMS1 and COMS2), and resistor value (RSEG) between
power supply pins V1OUT, V3OUT, V4OUT, GND and segment signal pins (SEG1 to SEG72 (96)),
when current Id is flown through all driver output pins.
9. This excludes the current flowing through pull-up MOSs and output drive MOSs.
10. 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.
11. The following shows the relationship between the operation frequency (fosc) and current consumption
(Icc) (figure 60).
