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
