nRF5840 I2S interface

[Ahmad K.H.]

Hello 

we are working on Audio project with nRF52840  include  (microphone and Audio Amp). we used one I2S interface for Audio Amplifier but for Microphone we are confused  : Has nRF52840 more than one i2S interface ( one for AMP another for Microphone) or we have to use PDM microphone

Hi,

There is only one I2S interface on the nRF52840. There is also a single PDM peripheral.
