Horizontal zoom factor. When other than 1
×
zoom is selected, the internal pixel
multiplier is configured such that it loads pixel data at a reduced rate. Also, the
RCLK frequency must be modified to facilitate the new reduced rate. The new
RCLK frequency should be chosen as the old RCLK frequency divided by the
zoom factor The horizontal zoom function applies only to the pixel port
zoom factor. The horizontal zoom function applies only to the pixel port
(P127–P0) data. VGA data cannot be zoomed.

Color-Key (Overlay, Red, Green, Blue) Registers (Index: 0x30–0x37,
Access: R/W, Default: Uninitialized)
These registers are used to specify the color comparison ranges for the four direct-color data fields when
performing color-key switching. A low and a high register are provided for each of the four data fields to
facilitate the range comparison. See Section 2.10 for more details on their usage. There are eight registers
total, two for each color. The formats for both low and high registers are shown below. Values 0 to 0xFF may
be written into the four color key low and four color key high registers.
