8.11.7 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 that 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.
Note: 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 display off by the display
control bit of the OSD control register (address 00EA16), an OSD inter-
rupt request does not occur (refer to Figure 8.11.16).
