Although wide operating voltage range is warranted, and exemption to it is when an access made by
MPU is accompanied with radical voltage fluctuations.

It is applicable when D0 to D5, D6(SCL) and D7(SI) pins are placed in high impedance.
It represents the resistance value to be employed when 0.1V is applied across the output pin SEGn

For the relationship between the oscillating frequency and frame frequency, refer to Table 6.
External inputs listed in the standard value space are recommended values.
Adjustment of the V
the voltage follower circuit.
The built-in oscillation circuit is used. It indicates current consumed by the independent IC when
the display is turned on.
It does not include current consumed due to the LCD panel capacity or wiring capacity (driver
output is under no-load).
These values are applicable when the access is not made by MPU.
