Latency
Hello, The aim of my project is to implement an ANC system for noise cancellation in ducts below 300Hz, so the reference and error microphones can be placed at big distances (1m for example = 3ms dela

Reset RAM via MCU
Hey Team, Is there a way to clear the DSP RAM via SPI from a MCU ? The datasheet says that after a hardware reset the RAM is not guaranteed to be cleared. I implemented a DSP firmware update mechanism
