ALPHA2_X_END
Description
Reserved (Read Only). Reads back as 0.
Load Alpha (Write Only). When set to 1, this bit causes the video processor to load the
alpha value (bits [7:0]) at the start of the next frame. This bit is cleared by the de-asser-
tion of VSYNC.
Alpha Window 1 Enable. Enable bit for alpha window 1.
0: Disable alpha window 1.
1: Enable alpha window 1.
Alpha Window 1 Increment. Specifies the alpha value increment/decrement. This is a
signed 8-bit value that is added to the alpha value for each frame. The MSB (bit 15) indi-
cates the sign (i.e., increment or decrement). When this value reaches either the maxi-
mum or the minimum alpha value (255 or 0), it keeps that value (i.e., it is not
incremented/decremented) until it is reloaded via bit 17.
Alpha Window 1 Value. Specifies the alpha value to be used for this window.
Description
Reserved (Read Only). Reads back as 0.
Alpha Window 2 X End. Indicates the horizontal end position of alpha window 2. This
value is calculated according to the following formula:
Value = Desired screen position + (H_TOTAL – H_SYNC_END) – 1. (Note 1)
Reserved (Read Only). Reads back as 0.
Alpha Window 2 X Start. Indicates the horizontal start position of alpha window 2. This
value is calculated according to the following formula:
Value = Desired screen position + (H_TOTAL – H_SYNC_END) – 2. (Note 1)
