22.2.3 Modes of Operation
The LCD64F6B module supports up to seven operation modes with different numbers of backplanes and
different biasing levels.During power saving mode the LCD operation can be suspended under software
control. Depending on the state of internal bits, the LCD can operate normally with source clock applied,
or the LCD clock generation can be turned off and the LCD64F6B module enters a power conservation
state.
This is a high level description only, detailed descriptions of operating modes are contained in later
sections.
