registers 59h to 5BH, There are programmable offsets in the horizontal and vertical direction available: parameters HOFF[10:0] 5BH[2:0] 59H[7:0],
VOFF[8:0] 5BH[4] 5AH[7:0], FOFF[5BH[7]] and VEP[5BH[5]]). I.e. these control registers are defining the decoder data output format - active video, raw
samples (optionally a test line), which is delivered from combfilter video decoder output to the expansion port output, the scaler and the VBI Data Slicer.
Table 7 Relationship of LCR to line numbers in 525 lines/60 Hz systems (part 1)
Vertical line offset, VOFF[8:0] = 06H,resp. 03H (subaddresses 5BH[4] and 5AH[7:0]); horizontal pixel offset, HOFF[10:0] = 347H (subaddresses 5BH[2:0]
and 59H[7:0]); FOFF = 1 (subaddress 5BH[7]), VEP = 0 (subaddress 5BH[5])
