Selection of field to be sliced data
In the case of the main data slice line, the field to be sliced data is
selected by bits 2 and 1 of the data slicer control register 1 (address
00EA
16
). In the case of the sub-data slice line, the field is selected
by bits 2 and 1 of the data slicer control register 3. When bit 2 of
the data slicer control register 1 is set to “1,” it is possible to slice
data of both fields (refer to Figure 20).
Specification of line to set slice voltage
The reference voltage for slicing (slice voltage) is generated by
integrating the amplitude of the clock run-in pulse in the particular
line (refer to Table 3).
Field determination
The field determination flag can be read out by bit 5 of the data
slicer control register 1. This flag charge at the falling edge of
V
sep
.

(5) Data Slice Line Specification Circuit
Specification of data slice line
M37270MF-XXXSP has 2 data slice line specification circuits for
slicing arbitrary 2 H
sep
in 1 field. The following 2 data slice lines
are specified .
<Main data slice line>
This line is specified by the caption position register (address
00E0
16
).
<Sub-data slice line>
This line is specified by the data slicer control register 3 (address
00EB
16
).
The counter is reset at the falling edge of V
sep
and is incremented
by 1 every H
sep
pulse. When the counter value matched the value
specified by bits 4 to 0 of the caption position register (in case of
the sub-data slice line, by bits 3 to 7 of the data slicer control register
3), this H
sep
is sliced.
The values of “00
16
” to “1F
16
” can be set in the caption position
register. Bit 7 to bit 5 are used for testing. Set “100
2
.” Figure 24
shows the signals in the vertical blanking interval. Figure 25 shows
the structure of the caption position register.
