9.2
The LCD module has several external pins dedicated to power supply and also LCD frontplane/backplane
signaling.
device-specific pin configurations.
9.2.1
This output signal vector represents the analog backplane waveforms of the LCD module. These signals
are connected to the back plane of the LCD panel.
9.2.2
This output signal vector represents the analog frontplane waveforms of the LCD module. These signals
are connected to the front plane of the LCD panel.
9.2.3
This signal vector represents either an analog frontplane or backplane waveform of the LCD module
depending on the configuration of the DUTY[1:0] bit field.
