8.11.3 Dot Size
The dot size can be selected by a block unit. The dot size in vertical
direction is determined by dividing H
SYNC
in the vertical dot size con-
trol circuit. The dot size in horizontal 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, OSC1,
main clock) in the pre-divide circuit. The clock cycle divided in the
pre-divide circuit is defined as 1T
C
.
The dot size is specified by bits 6 to 3 of the block control register.

In normal scan mode
Refer to Figure 8.11.4 (the block control register i), refer to Figure
8.11.6 (the clock control register).
The block diagram of dot size control circuit is shown in Figure 8.11.14.
Notes 1:
The pre-divide ratio = 3 cannot be used in the CC mode.
2:
The pre-divide ratio of the layer 2 must be same as that of the layer 1
by the block control register i.
3:
In the bi-scan mode, the dot size in the vertical direction is 2 times as
ompared with the normal mode. Refer to
8.11.13 Scan Mode
about
the scan mode.
