Fig. 8.11.10 Block Diagram of Dot Size Control Circuit
8.11.2 Dot Size
The dot size can be selected in block units. The vertical dot size is
determined by dividing HSYNC in the vertical dot size control circuit.
The horizontal dot size is determined by dividing the following clock
in the horizontal dot size control circuit : the clock gained by dividing
the OSD clock source (data slicer clock, f (OSC) in the pre-divide
circuit. The clock cycle divided in the pre-divide circuit is defined as
1TC.
The dot size of each block is specified by bits 2 to 4 of block control
register i.
Refer to Figure 8.11.4 for the structure of the block control register.
The block diagram of the dot size control circuit is shown in Figure

8.11.10.
The pre-divide ratio is specified by bit 7 of the OSD control register
(address 00D016) and bit 4 of block control register i (addresses
00D216 and 00D316) .
When bit 7 of the OSD control register (address 00D016) is set to
"0," the double or triple pre-divide ratio can be chosen per block unit
by bit 4 of block control register i. And then, when it is set to "1", the
pre-divide ratio increases 1 time (both blocks 1 and 2). The pre-di-
vided dot size can be specified per block unit by bits 2 and 3 of block
control register i.
