bit 4

FPLINE Polarity

 

This bit controls the polarity of FPLINE in TFT/D-TFD mode (no effect in passive panel

 

mode). When this bit = 0, FPLINE is active low. When this bit = 1, FPLINE is active high.

bit 3

FPFRAME Polarity

 

This bit controls the polarity of FPFRAME in TFT/D-TFD mode (no effect in passive

 

panel mode). When this bit = 0, FPFRAME is active low. When this bit = 1, FPFRAME is

 

active high.

bit 2

Mask FPSHIFT

 

FPSHIFT is masked during non-display periods if either of the following two criteria is

 

met:

 

1. Color passive panel is selected (REG[01h] bit 5 = 1)

 

2. This bit (REG[01h] bit 2) = 1

bits 1-0

Data Width Bits [1:0]

 

These bits select the display data format. See Table 8-1: “Panel Data Format” below for a

 

comprehensive description of panel selection.
