The vertical position for each block can be set in 1024 steps (where each step is 1TH (TH: HSYNC cycle))
as values “00216” to “3FF16” in vertical position register i (i = 1 to 16) (addresses 022016 to 023F16). The
vertical position register i is shown in Figure 2.16.10.

Nothing is assined.
In an attempt to write to this bit, write “0.”
The value, if read, turns out to be indeterminate.
Note : Do not set VPi ≤ “00116,” VPi ≥ “40016.”

The horizontal position is common to all blocks, and can be set in 256 steps (where 1 step is 4TOSC, TOSC
being OSD oscillation cycle) as values “0016” to “FF16” in bits 0 to 7 of the horizontal position register
(address 020416). The horizontal position register is shown in Figure 2.16.11.
