(Cautions)
It Quality of crystal oscillation wave form largely affect S/N ratio and noise distortion.
Further, this is also true then system clock is input externally through the XI terminal.
0 The wiring between the TC9296AF output and the TA2009F input must be made the
shortest.
o The condenser between VDD and GND shall be connected as close to the pin as possible.
