(1) Display position
The display positions of characters are specified by a block. There
are 2 blocks, blocks 1 and 2. Up to 24 characters can be displayed in
each block (refer to “(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 set for all
blocks in common in 64-step display positions in units of 4T
OSC
(T
OSC
= OSD oscillation cycle).
The display start position in the vertical direction for each block can
be set in 255-step display positions in units of 1 H ( H = H
SYNC
cycle).
Blocks are displayed in conformance with the following rules:
When the display position of block 1 is overlapped with block 2
(Figure 8.10.9 (b)), block 1 is displayed on the front.
When another block display position appears while one block is .
displayed (Figure 8.10.9 (c)), the block with a larger set value as
the vertical display start position is displayed.
For the display position of SPRITE display, it is necessary to set in-
dependently, and it is possible to set display positions independently.
Refer to “8.10.2 SPRITE Display.”
