(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 of the layer 1 is specified by bits 6 to 3 of the block
control register.
The dot size of the layer 2 is specified by the following bits : bits 3
and 4 of the block control register, bit 6 of the clock source control
register. Refer to Figure 56 (the structure of the block control regis-
ter), refer to Figure 65 (the structure of the clock source control reg-
ister).
The block diagram of dot size control circuit is shown in Figure 64.
Notes 1 :
The pre-divide ratio = 3 cannot be used in the CC mode.
2 :
The pre-divide ratio of the OSD mode block on the layer 2
must be same as that of the CC mode block on the layer 1
by bit 6 of the clock source control register.
3 :
In the bi-scan mode, the dot size in the vertical direction is
2 times as compared with the normal mode. Refer to “(13)
Scan Mode” about the scan mode.
