Note how to use this IC
Power-on Reset
Input signal with sufficient low impedance to input terminal.
The capacitance of output terminal as small as possible.
Set the capacitance between Vcc and GND near the pins if possible.
Assign an area as large as possible for grounding.
The M52797 has an intermal power-on reset function that sets each
control r egister to "0" during IC power ON.
