8.10.1 Display Position
The display positions of characters are specified in units called a
“block.” There are 2 blocks, blocks 1 and 2. Up to 24 characters can
be displayed in each block (refer to “8.10.3 Memory for OSD”).
The display position of each block can be set in both horizontal and
vertical directions by software.
The display start position in the horizontal direction can be selected
for all blocks in common from 64-step display positions in units of
4T
The display start position in the vertical direction for each block can
be selected from 128-step display positions in units of 4 scanning
lines.
