Horizontal Display Period Bits [6:0]
These bits specify the LCD panel Horizontal Display period, in 8 pixel resolution. The
Horizontal Display period should be less than the Horizontal Total to allow for a
sufficient Horizontal Non-Display period.
Horizontal Display Period in number of pixels = (Bits [6:0] + 1) x 8
Note
Maximum value of REG[14h] ≤ 0x3F when Display Rotate Mode (90° or 270°) is
selected.
For panel AC timing and timing parameter definitions, see Section 10.4 “Display
Interface”.
Horizontal Display Period Start Position Bits [9:0]
These bits specify the Horizontal Display Period Start Position in 1 pixel resolution.
Note
For panel AC timing and timing parameter definitions, see Section 10.4 “Display
Interface”.
