(*1) No CPU access state.
No LCD panel load.
Other conditions: 1/12 bias; contrast = 60; internal resistance ratio setting = 5.8; 3-FRC; 9-level
PWM; frame inversion
(*2) The current consumption is a sum of V
DD
current and VCI current.
(*3) Vref voltage is measurable in the test mode, but cannot be measured when a customer is using the
ML9055A in normal circumstances.
