Description

I2S Status Feedback Register. Contains status information about the I2S interface.

Fields

IRQ

This bit reflects the presence of Receive Interrupt or Transmit Interrupt. This is determined by comparing the current FIFO levels to the rx_depth_irq and tx_depth_irq fields in the IRQ register.

DMAREQ1

This bit reflects the presence of Receive or Transmit DMA Request 1. This is determined by comparing the current FIFO levels to the rx_depth_dma1 and tx_depth_dma1 fields in the DMA1 register.

DMAREQ2

This bit reflects the presence of Receive or Transmit DMA Request 2. This is determined by comparing the current FIFO levels to the rx_depth_dma2 and tx_depth_dma2 fields in the DMA2 register.

RESERVED

Reserved.

RX_LEVEL

Reflects the current level of the Receive FIFO.

RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.

TX_LEVEL

Reflects the current level of the Transmit FIFO.

RESERVED

Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined.
