8.11.1 Display Position
Blocks are displayed in conformance with the following rules:
• Block 2 is displayed after the display of block 1 is completed (Figure
8.11.4 (a)).
The display positions of characters are specified in units called
“blocks.” There are 2 blocks : blocks 1 and 2. Up to 24 characters
can be displayed in each block (refer to “8.11.3 Memory for OSD”).
The display position of each block can be set in both horizontal and
vertical directions by software.
• When the display position of block 1 is overlapped with that of block
2 (Figure 8.11.4 (b)), block 1 is displayed in front.
• When another block display position appears while one block is
displayed (Figure 8.11.4 (c)),only block 1 is displayed. Similarly,
when multiline display, block 1 is displayed after the display of block
2 is completed.
The display start position in the horizontal direction can be selected
for all blocks from 64-step display positions in units of 4TC (TC =
OSD oscillation cycle).
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.
