SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
The horizontal position is common to all blocks, and can be set in
256 steps (where 1 step is 4TOSC, TOSC being the oscillating cycle
for display) as values “0016” to “FF16” in bits 0 to 7 of the horizontal
position register (address 00CF16). The structure of the horizontal
position register is shown in Figure 72.
