■ Mono/Stereo Mode
PMAD1-0 and 3-2 bits set mono/stereo mode of ADC1 and ADC2 operation, respectively. When changing ADC operation
and analog/digital microphone, PMAD3-0 bits must be set “0” at first. When DMIC bit = “1”, PMAD3-0 bits settings are
ignored. When DMIC bit = “0”, PMDM3-0 bits settings are ignored. MMODE bit must be set to “1” (default: “0”) when
power up an ADC (PMADx bit = “1”).
