Hi Team,

Is it possible to connect TDM microphone directly into PCM interface of DA1469x?

In the DA1469x datasheet it is mentioned as follows.

Audio blocks: This part enables audio streaming by means of a Pulse Density Modulation (PDM), a Sample Rate Converter (SRC) and a Pulse Code Modulation (PCM) interface. It can support up to 2 digital microphones or 2 digital loudspeakers using the PDM interface or connect an external CoDec at the PCM/I2S interface.

Only ext. CoDec can be connected at the PCM/I2S interface. Please clarify. I am new to this audio world :-)
