35.6.7 I2S DMA Configuration Register 2
35.6.8 I2S Interrupt Request Control register
The DMA2 register controls the operation of DMA request 2. The function of bits in DMA2
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
configured for 32-bit mode (see
level is 4.
The IRQ register controls the operation of the I2S interrupt request. The function of bits in
IRQ are shown in
Description
When 1, enables I2S receive interrupt.
When 1, enables I2S transmit interrupt.
Reserved.
Set the FIFO level on which to create an irq request.
Description
When 1, enables DMA1 for I2S receive.
When 1, enables DMA1 for I2S transmit.
Reserved.
Reserved, user software should not write ones to reserved bits. The value read
from a reserved bit is not defined.
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 DMA2.
Set the FIFO level that triggers a transmit DMA request on DMA2.
Description
