Table 218
Horizontal input window length; register set A [96H[7:0]; 97H[3:0]] and B [C6H[7:0]; C7H[3:0]]
Note
1.
Reference for counting are luminance samples.
Table 219
Vertical input window start; register set A [98H[7:0]; 99H[3:0]] and B [C8H[7:0]; C9H[3:0]]
Note
1.
For trigger condition: STRC[1:0] 90H[1:0] = 00; YO + YS > (number of input lines per field
2), will result in field
dropping. Other trigger conditions: YO > (number of input lines per field
2), will result in field dropping.
Table 220
Vertical input window length; register set A [9AH[7:0]; 9BH[3:0]] and B [CAH[7:0]; CBH[3:0]]
Note
1.
For trigger condition: STRC[1:0] 90H[1:0] = 00; YO + YS > (number of input lines per field
2), will result in field
dropping. Other trigger conditions: YS > (number of input lines per field
