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 for DFS="L",
17408 LRCK cycles for DFS ="H".
Reset Pin
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.
