Serial Interface Mode Select Pin
Left/Right Channel Select Clock Pin
Normally connected to GNDL with a 10µF electrolytic capacitor and
a 0.1µF ceramic capacitor.
This pin controls the calibration reference signal.
"L": VCOML and VCOMR
"H": Analog Input Pins (AINL , AINR )
"H" means the offset calibration cycle is in progress. Offset calibration starts
when RST goes "H". CAL goes "L" after 8704 LRCK cycles for DFS="L",
17408 LRCK cycles for DFS ="H".
When "L", Digital section is powered-down. Upon returning "H", an
offset calibration cycle is started. An offset calibration cycle should always
be initiated after power-up.
MSB first, 2's compliment.
SMODE2 SMODE1
LRCK goes "H" at SMODE2="L" and "L" at SMODE2="H" during reset
when SMODE1 "H".
