Fig. 60. Display Counter
Fig. 61. Timing of CRT Interrupt Request and Display Counter Value
The display block counter counts the number of times the display of
a block has been completed, and its contents are incremented by 1
each time the display of one block is completed.
To provide multi-line display, enable CRT interrupts by clearing the
interrupt disable flag to “0” and setting the CRT interrupt enable bit
(bit 4 of address 00FE16) to “1.” After that, process the following
sequence within the CRT interrupt processing routine:
ead the value of the display block counter.
The block for which display is terminated (i.e., the cause of CRT
interrupt generation) can be determined by the value read in
.
Replace the display character data and vertical display position of
that block with the character data (contents of CRT display RAM)
and vertical display position (contents of vertical position register)
to be displayed next.
Figure 60 shows the structure of the display block counter.
