The I2S:STMPINTRIG and I2S:STMPOUTTRIG registers contain I2S:STMPWCNT compare values that are used to start the input and output DMA, respectively:
To avoid false start-up triggers, I2S:STMPINTRIG and I2S:STMPOUTTRIG must initially be equal to or higher than I2S:STMPWPER.
The I2S:STMPCTL.IN_RDY and I2S:STMPCTL.OUT_RDY status bits are set when the input and output DMA are ready to be started and cleared when DMA start triggers have occurred.
