NOTES:
1.
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.
CS1B, CS2, RS, DB7 to DB0, E_RD, RW_WR, RESETB, MS, MI, PS, TEMPS, CL, M, DISP pins
DB7 to DB0, M, FRS, DISP, CL pins
CS1B, CS2, RS, DB7 to DB0, E_RD, RW_WR, RESETB, MS, MI, PS, TEMPS, CL, M, DISP pins
Applies when the DB7 to DB0, M, DISP, and CL pins are in high impedance.

See Table 17 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
consumption, when the built-in power supply circuit is on or off. 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.
