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.
