Double Pixel Clock mode:

0 = The L_PCLK pin is driven at the frequency specified by PCD.

1 = The L_PCLK pin is driven at double the frequency specified by PCD.

Bits Per Pixel:

000 – 1-bits/pixel [4 entry, 8 byte palette buffer (only first 2 entries are used)]

001– 2-bits/pixel [4 entry, 8 byte palette buffer]

010– 4-bits/pixel [16 entry, 32 byte palette buffer]

011– 8-bits/pixel [256 entry, 512 byte palette buffer]

100– 16-bits/pixel [no palette buffer] 101, 110, 111 – reserved

Output Enable Polarity:

0 = L_BIAS pin is active high and inactive low in active display mode.

1 = L_BIAS pin is active low and inactive high in active display mode.

In active display mode, data is driven out to the LCD’s data pins on the programmed pixel clock edge when the L_BIAS pin is active. OEP is ignored in passive display mode.

Pixel Clock Polarity:

0 = Data is sampled on the LCD data pins on the rising edge of L_PCLK. 1 = Data is sampled on the LCD data pins on the falling edge of L_PCLK.

Horizontal Sync Polarity:

0 = L_LCLK pin is active high and inactive low. 1 = L_LCLK pin is active low and inactive high.

Vertical Sync Polarity:

0 = L_FCLK pin is active high and inactive low. 1 = L_FCLK pin is active low and inactive high.
