Calibration Active Signal Pin
"H" means the offset calibration cycle is in progress. Offset calibration starts
when RST goes "H". CAL goes "L" after 8704 LRCK cycles.

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.
