18.2.5.8
Table 221 Horizontal output window length; register set A [9CH[7:0]; 9DH[3:0]] and B [CCH[7:0]; CDH[3:0]]
Notes
1. Reference for counting are luminance samples.
2. If the desired output length is greater than the number of scaled output pixels, the last scaled pixel is repeated.
Table 222 Vertical output window length; register set A [9EH[7:0]; 9FH[3:0]] and B [CEH[7:0]; CFH[3:0]]
Note
1. If the desired output length is greater than the number of scaled output lines, the processing is cut.
