and ON-SCREEN DISPLAY CONTROLLER
M37273M8-XXXSP
M37273E8SP
(10) Multiline Display
The M37273M8-XXXSP can ordinarily display 2 lines on the CRT
screen by displaying 2 blocks at different vertical positions. In addi-
tion, 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 reg-
ister (addresses 00D216, 00D316), an OSD interrupt request
does not occur (refer to Figure 67 (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 67 (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 67 (C)).
