Product Number: AD2437
Good morning,
am working with a custom board based on an AD2437 chip that uses a PDM microphone connected to SIO0, along with two RX and two TX channels. I would now like to transmit the signal coming from RX0 without taking the PDM0 signal into account. My question is the following: how does the chip handle the RX and PDM inputs? Is the signal on SIO0 (therefore PDM0) processed first, or do RX0 and RX1 have priority?
Because if I disable PDM0, the system by default maps RX0 to SIO0, but it is physically connected to SIO1. If the chip processes PDM0 first, in order to transmit only what the chip receives from RX0 and RX1, is it sufficient to set A2B_DNOFFSET and A2B_UPOFFSET to manage this behavior?
