MITSUBISHI MICROCOMPUTERS
DATA SLICER
The M37274EFSP 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
composite 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 can
be cut off by setting bit 0 of data slicer control register 1 (address
00EA16) to “0.” Also, the timing signal generating circuit can be cut
off by setting bit 0 of data slicer control register 2 (address 00EB16)
to “0.” These settings can realize the low-power dissipation.

Note: Make the length of wiring which is

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.
