"L":VCOML and VCOMR
"H":Analog Input Pins(AINL±,AINR±)
Normally connected to GNDL with a 10uF electrolytic capacitor and
a 0.1uF ceramic capacitor
This pin controls the calibration reference signal.
"H" means the offset calibration cycle is in progress. Offset calibration starts
when
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.
LRCK goes "H" at SMODE2="L" and "L" at SMODE2="H" during reset
when SMODE1 "H".
