4.1 Register Summary
4.2 Register Table
AO_STATUS—DTL Clock Domain
The following tables illustrate the register set of the Audio Out block. Access to these
registers is via the DTL port. These registers are distributed between the DTL clock
domain (DCS/MMIO bus), the DMA clock domain (MTL/DDR bus) and the IP clock
domain, i.e. the AO module clock. The access time to these registers is proportional
to the clock domain frequency with respect to the CPU speed.

Description
Provides status of buffers and other Audio Out components/situations.
Control register to configure Audio Out options
Control register to configure Audio Out serial timing and data options
Control register to configure data framing
Base address of DMA buffer 1 in memory
Base address of DMA buffer 2 in memory
The DMA Buffer size in samples
Codec Control data content
Codec data position
Powerdown function
Provides module ID number, including major and minor revision levels.
Description
To ensure software backward compatibility unused or reserved bits must
be written as zeros and ignored upon read
0 = Audio Out is ready to receive a CC1, CC2 pair.
1 = Audio Out is not ready to receive a CC1, CC2 pair. Try again in a
few SCK clock intervals.
1 =DMA buffer 1 in memory will be used for the next sample to be
transmitted.
0 =DMA buffer 2 in memory will contain the next sample.
