This register defines the horizontal total sampled pixels between 2 continuous input
horizontal sync. The actual number is defined as: PllDiv * 16
Make sure that the value of (Graphic Clock PLL divider) * (Detected Vertical Total) *
(Detected Scan Rate) does not exceed the maximum speed of the field memory used, e.g.,
PllDiv * 16 * GinVTotal * 4 * VGArr <= 56MHz for AL422
PllDiv, GinVTotal and VGArr are defined by registers 28h, 43h and 44h respectively.
2Bh:
Delta of Horizontal Start in Zoom Mode (R/W) [GINHSTZOOMDLT]
GinHStZoomDlt <6:0>
(unit: 8 pixels) ** X Pan (in zoom mode) **
<7>
Reserved
This does not apply to non-zoom mode.
The actual horizontal capture start position is defined as:
(default horizontal capture start position) + (GinHStZoomDlt * 8).
The value of GinHStZoomDlt is signed, and its range is between –64 and 63.
Please refer to Section 8.3, AL128 Plug & Play Hardware Table for the default horizontal
capture start positions.
2Ch:
Delta of Vertical Start in Zoom Mode (R/W) [GINVSTZOOMDLT]
GinVStZoomDlt <6:0>
(unit: 4 lines) ** Y Pan (in zoom mode) **
<7>
Reserved
This does not apply to non-zoom mode.
The actual vertical capture start position is defined as:
(default vertical capture start position) + (GinVStZoomDlt * 4).
The value of GinVStZoomDlt is signed, and its range is between -64 and 63.
Please refer to Section 8.3, AL128 Plug & Play Hardware Table for the default vertical
capture start positions.
