Description
Reserved (Read Only). Reads back as 0.
Video Y End Position. Represents the vertical end position of the video window. This
value is calculated according to the following formula:
Value = Desired screen position + (V_TOTAL – V_SYNC_END) + 2. (Note 1)
Reserved (Read Only). Reads back as 0.
Video Y Start Position. Represents the vertical start position of the video window. This
register is programmed relative to CRT Vertical sync input (not the physical screen posi-
tion). This value is calculated according to the following formula:
Value = Desired screen position + (V_TOTAL – V_SYNC_END) + 1. (Note 1)
Description
Reserved (Read Only). Reads back as 0.
Alpha Window 1 Y End. Indicates the vertical end position of alpha window 1. This value
is calculated according to the following formula:
Value = Desired screen position + (V_TOTAL – V_SYNC_END) + 2. (Note 1)
Reserved (Read Only). Reads back as 0.
Alpha Window 1 Y Start. Indicates the vertical start position of alpha window 1. This
value is calculated according to the following formula:
Value = Desired screen position + (V_TOTAL – V_SYNC_END) + 1. (Note 1)
