Microphone Data Readout and Test Registers (OUTDATA1) – Offset 10208
These registers are the single address locations that DMA data transfers should access.
\t It exposes a port from the FIFO. The CPU / DMA read these registers to drain the Asynchronous FIFO.
\t The FIFO control logic transfers next data automatically from Synchronous FIFO as fast as possible.
\t The software should make sure that the Asynchronous FIFO threshold is set equal or greater than the burst size specified for the DMA controller to avoid stalling the interconnect during transactions.
\t The speed of refilling the asynchronous FIFO from Synchronous FIFO determines the gap between burst transactions on the bus.
\t The software may use write into these locations for test purposes. The write places the written data into the input of Synchronous FIFO.
\t The test writes will only work if the OUTCTRL.SIP bit is cleared.
