Description
Reserved (Read Only). Reads back as 0.
Spare. Bit is read/write, but has no function.
TFT Pass Through. Activates the TFT Pass Through mode. In TFT Pass Through
mode, the input timing and the pixel data is passed directly on to the panel interface tim-
ing and the panel data pins to drive the TFT panel. In Pass Through mode the internal FP
TFT logic and timing is not used.
0: Normal mode; uses the TFT logic and timing from the FP.
1: TFT Pass Through mode; FP TFT timing logic functions are not used.
Display Timing Strobe Polarity Select. Selects the polarity of the LDE/MOD pin. This
can be used for panels that require an active low timing LDE interface signal.
0: LDE/MOD signal is active high. (Default)
1: LDE/MOD signal is active low
Reserved. This bit is not defined.
Panel Shift Clock Retrace Activity Control. Programs the shift clock (SHFCLK) to be
either free running, or active only during the display period. Some TFT panels recom-
mend keeping the shift clock running during the retrace time.
0: Shift clock is active only during active display period.
1: Shift clock is free running during the entire frame period.
Reserved. These bits are not defined.
Vertical Sync Output Polarity. Selects polarity of the output VSYNC signal. Note that
VP Memory Offset 400h[30] selects the polarity of the input VSYNC.
0: VSYNC output is active high.
1: VSYNC output is active low
Horizontal Sync Output Polarity. Selects polarity of output HSYNC signal. Note that
VP Memory Offset 400h[29] selects the polarity of the input HSYNC, and this bit controls
the output polarity.
0: HSYNC output is active high.
1: HSYNC output is active low
Reserved. These bits are not defined.
Color/Mono Select. Selects color or monochrome LCD panel.
0: Color.
1: Monochrome.
