The following caution is also added to EXT
mode:
“If PS1-0 bits are changed before LRCK is
input, MCKO is not output. PS1-0 bits should
be changed after LRCK is input in slave mode.”
“If both Lch and Rch input signals are lower
than the “ALC1 Recovery Waiting Counter
Reset Level”, the ALC1 recovery operation
starts.”

Mono Line Output from the MOUT+ and
MOUT- pins are centered at 0.45 x AVDD.”
“If the sampling frequency is changed and the
PLL goes to unlock state when the DAC is
operated(PMDAC bit=“1”), the DAC data
should be soft-muted or “0”. In case of the
ADC(PMADL bit = “1” or PMADR bit = “1”),
the ADC data acquired during the frequency
change may be erroneous and therefore should
not be used.” is deleted.
