4.3.5 Output timing of sub-sampling
4.3.5.1 Sub-sampling VGA(640X480) from (1288 X 968 ) windowing:
(with 4 column and 2 row for color interpolation)
cf[1:0] = 1, rf[1:0]=1, sub-sampling rate (1/2,1/2),
wcp[10:0]=0, wcw_in[10:0]=1287, column pixels 644=(1287+1)/2,
wrp[10:0]=0,wrd[10:0]=963, row pixel 484=(963+1)/2,
cm =1, single_path = 1, row_ave= 1, CDS_ext2_in =1.
