6. The TEST pin must be grounded and the ID5 to ID0, IM1, IM0, SFT, EXM, and OPOFF pins must
be grounded or connected to V
CC
.
7. Applies to the ACK bit for I
8. Applies to resistor values (RCOM) between power supply pins V
CC
, V1OUT, V4OUT, V5OUT and
common signal pins (COM1 to COM32, COMS1, and COMS2), and resistor values (RSEG) between
power supply pins V
CC
, V2OUT, V3OUT, V5OUT and segment signal pins (SEG1 to SEG60).
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 (f
OSC
) and current consumption
(I
CC
) (Figure 47).
