Though the wide range of operating voltages is guaranteed, a spike voltage change may affect the voltage assurance
during access from MPU.
In case of external power supply is applied.

Applies when the DB0
DB7, M, DISP, and CL pins are in high impedance.
Resistance value when
±
0.1[mA] is applied during the ON status of the output pin SEGn or COMn.
R

=
V / 0.1 [k
] (
V: voltage change when
±
0.1[mA] is applied in the ON status.)
See Table 18 for the relationship between oscillation frequency and frame frequency.
The voltage regulator circuit adjusts V0 within the voltage follower operating voltage range.
10. On-chip reference voltage source of the voltage regulator circuit to adjust V0.
11. Applies to the case where the on-chip oscillation circuit is used and no access is made from the MPU.
The current flowing through voltage regulation resistors (Rb and Ra) is not included. It does not include the current of
the LCD panel capacity, wiring capacity, etc.
