SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER
and ON-SCREEN DISPLAY CONTROLLER
64
(8) Multiline Display
This microcomputer can ordinarily display 3 lines on the CRT screen
by displaying 3 blocks at different vertical positions. In addition, it can
display up to 16 lines by using CRT interrupts.
A CRT 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.
Note:
A CRT 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 with the display control bit of the CRT control reg-
ister 1 (address 00EA
16
), a CRT interrupt request does not
occur (refer to Figure 59).
