35.6.5 I2S Status Feedback register
35.6.6 I2S DMA Configuration Register 1
Description
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.
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.
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.
Reflects the current level of the Receive FIFO.
Reserved, user software should not write ones to reserved bits. The value read from a
reserved bit is not defined.
Reflects the current level of the Transmit FIFO.
Reserved, user software should not write ones to reserved bits. The value read from a
reserved bit is not defined.
The STATE register provides status information about the I2S interface. The meaning of
bits in STATE are shown in
The DMA1 register controls the operation of DMA request 1. The function of bits in DMA1
are shown in

This register enables the DMA for the I
FIFO level.
Remark: The FIFOs contain eight 16-bit words. Therefore, if the I

level is 4.
Description
When 1, enables DMA1 for I2S receive.
When 1, enables DMA1 for I2S transmit.
Reserved, user software should not write ones to reserved bits. The value read
from a reserved bit is not defined.
Set the FIFO level that triggers a receive DMA request on DMA1.
