When using a microphone that supports multiplexed operation (2-mics
can share a common data line), configure the microphone for “Left” and
select mono operation using the vendor specific verb.
“Left” D-mic data is used for ADC left and right channels.
Available on either DMIC_0 or DMIC_1, External logic required to support
sampling on a single Digital Mic pin channel on rising edge and second
Digital Mic right channel on falling edge of DMIC_CLK for those digital
microphones that don’t support alternative clock edge (multiplexed output)
capability.
Requires both DMIC_0 and DMIC_1, External logic required to support
sampling on a single Digital Mic pin channel on rising edge and second
Digital Mic right channel on falling edge of DMIC_CLK for those digital
microphones that don’t support alternative clock edge (multiplexed output)
capability. Two ADC units are required to support this configuration
Connected to DMIC_0 and DMIC_1, External logic required to support
