SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
The vertical display start position for each block can be set in 512
steps (where each step is 1TH (TH: HSYNC cycle)) as values “0016” to
“FF16” in vertical position register i (i = 1 and 2) (addresses 00D416
and 00D516) and values “0” or “1” in bit 6 of block control register i (i
= 1 and 2) (addresses 00D216 and 00D316). The vertical position
registers is shown in Figure 8.11.7.

Functions
Vertical display start position =
TH ! (BCi6 ! 16² + n)
(n: setting value, TH: HSYNC cycle,
BCi6: bit 6 of block control register i)
Note: Set values except “0016” to VPi when BCi6 is “0.”
