Rev 1.0
8.11.10 Multiline Display
This microcomputer can ordinarily display 2 lines on the CRT screen
by displaying 2 blocks at different vertical positions. In addition, it can
display up to 16 lines by using OSD interrupts.
An OSD interrupt request occurs at the point at which display of each
block has been completed. In other words, when a scanning line
reaches the point of the display position (specified by the vertical
position registers) of a certain block, the character display of that
block starts, and an interrupt occurs at the point at which the scan-
ning line exceeds the block.
Notes 1:
An OSD interrupt does not occur at the end of display when the block
is not displayed. In other words, if a block is set to off display by the
display control bit of the block control register (addresses 00D2
16
,
00D3
16
), an OSD interrupt request does not occur (refer to Figure
8.11.23 (A)).
2:
When another block display appeares while one block is displayed,
an OSD interrupt request occurs only once at the end of the another
block display (refer to Figure 8.11.23 (B)).
3:
On the screen setting window, an OSD interrupt occurs even at the
end of the CC mode block (off display) out of window (refer to Figure
8.11.23 (C)).
