Fig. 8.11.7 Vertical Position Register i (i = 1 and 2)

The vertical display start position for each block can be set in 512

steps (where each step is 1T

H (TH: HSYNC cycle)) as values “0016” to

“FF

16” in vertical position register i (i = 1 and 2) (addresses 00D416

and 00D516) and values “0” or “1” in bit 6 of block control register i (i

= 1 and 2) (addresses 00D2

16 and 00D316). The vertical position

registers is shown in Figure 8.11.7.
