Write Parameters
BYTE | BITS | DESCRIPTION |
---|---|---|
2:1 | 15:0 | Checksum Start Pixel Starting pixel coordinate in the active video data to checksum. This is 0-based. LSByte = Byte 1 |
4:3 | 15:0 | Checksum Start Line Starting line coordinate in the active video data to checksum. This is 0-based. LSByte = Byte 3 |
6:5 | 15:0 | Checksum Total Pixels Per Line Number of pixels in each active line to checksum. This is 1-based. LSByte = Byte 5 |
8:7 | 15:0 | Checksum Total Lines Per Frame Number of active lines in each frame to checksum. This is 1-based. LSByte = Byte 7 |
12:9 | 31:0 | Expected Checksum Expected checksum value for all pixels in the specified range. This value is only used for video tell-tale checksum. It may be set to 0 for video frame counter checksum. LSByte = Byte 9 |
