DAI/DPI Registers

The registers that are described in the following sections are contained
within the digital audio and digital peripheral interfaces. The bits in these
registers are used to enable the connection of peripherals and to view sta-
tus of data transfers. For complete information on using the DAI/DPI, see

once the required number of data transfers occurs. And even when DMA
through some channel is not intended, its
