*7. Resistance value when ±0.1[mA] is applied during the ON status of the output pin SEGn or COMn.
*8. See table 8-3 for the relationship between oscillation frequency and frame frequency.
*9. 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, 12. Applies to the case where the on-chip oscillation circuit is used and no access is made from the MPU.

RON = V / 0.1[k ] ( V :Voltage change when ±0.1[mA] is applied in the on status)
f
voltage assurance during access from the MPU
OSC
The current consumption, when the built -in power supply circuit is ON or OFF.
The current flowing through voltage regulation resistors (Ra and Rb) is not included.
It does not include the current of the LCD penal capacity, wiring capacity, etc.
