Panel Type Bits[2:0]
These bits select the panel type.
MOD Rate Bits [5:0]
When these bits are all 0, the MOD output signal (LDEN) toggles every LFRAME.
For any non-zero value n, the MOD output signal (LDEN) toggles every n LLINE.
These bits are for passive LCD panels only.
Horizontal Total Bits [6:0]
These bits specify the LCD panel Horizontal Total period, in 8 pixel resolution. The
Horizontal Total is the sum of the Horizontal Display period and the Horizontal Non-
Display period. The maximum Horizontal Total is 1024 pixels. See Figure 10-12 :
Panel Timing Parameters
Horizontal Total in number of pixels = (Bits [6:0] + 1) x 8
Note
This register must be programmed such that the following condition is fulfilled.
For panel AC timing and timing parameter definitions, see Section 10.4 “Display
Interface”.
