SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER

8.10 DATA SLICER
This microcomputer includes the data slicer function for the closed
caption decoder (referred to as the CCD). This function takes out the
caption data superimposed in the vertical blanking interval of a com-
posite video signal. A composite video signal, which makes the sync
chip’s polarity negative, is input to the CVIN pin.
When the data slicer function is not used, the data slicer circuit and
the timing signal generating circuit can be cut off by setting bit 0 of
data slicer control register 1 (address 00E016) to “0.” These settings
support the low-power dissipation.

Note : Make the length of wiring which is
connected to VHOLD, HLF, and CVIN pin as
short as possible so that a leakage current
may not be generated when mounting a
resistor or a capacitor on each pin.
