Panel data bus. Not all pins are used for some panels - see LCD
Interface Pin Mapping for details. Unused pins are driven low.
Frame pulse
Line pulse
Shift clock
LCD power control output. The active polarity of this output is selected
by the state of MD10 at the rising edge of RESET# - see Summary of
Configuration Options. This output is controlled by the power save
mode circuitry - see Power Save Modes for details.
This is a multi-purpose pin:
• For TFT/D-TFD panels this is the display enable output (DRDY).
• For passive LCD with Format 1 interface this is the 2nd Shift Clock
• For all other LCD panels this is the LCD backplane bias signal
See LCD Interface Pin Mapping and REG[02h] for details.
Horizontal retrace signal for CRT
Vertical retrace signal for CRT
Analog output for CRT color Red
Analog output for CRT color Green

Current reference for DAC - see Analog Pins. This pin must be left
unconnected if the DAC is not needed.
