I Power-down pin
Power-down mode is reached at the time of" H", Offset calibration star from" l", Calibration must be
executed once at the time of power ON and when the clock frequency has been changed,
9 CMODE I
Master clock selection pin " L ": CLK = 256fs (12,288MHz cg fs = 48kH)
" H ": CLK = 384fs (18.432MH cg fs = 48kH)
