LCDPWR Override
When this bit = 1, LCDPWR is forced inactive, by-passing the LCD power sequencing.
The 127 frame delay between Hardware Power Save and the LCD panel control signals is
reduced to a single line. When this bit = 0, LCDPWR is controlled by the power sequenc-
ing logic within the S1D13705. See Figure 7-9, “Power Down/Up Timing,” on page 1-26
for further information.
Hardware Power Save Enable
When this bit = 1 GPIO0 is used as the Hardware Power Save input pin. When this bit =
0, GPIO0 operates normally.
Software Power Save Bits [1: 0]
These bits select the Power Save Mode as shown in the following table.
Refer to Section 13 “Power Save Modes” on page 1-69 for a complete description of the
power save modes.
Horizontal Panel Size Bits [6:0]
This register determines the horizontal resolution of the panel. This register must be pro-
grammed with a value calculated as follows:
Note: This register must not be set to a value less than 03h.
