second buffer in memory as a request for a new first sample buffer in memory is
issued to the system controller. This action is repeated as the buffers in memory are
sent out.
The samples are given to the data serializer (parallel-to-serial converter), which
sends them out in a MSB first or LSB first serial frame format that can also contain
one or two codec control words of up to 16 bits. The output frame structure is
programmable.
The Audio Out module has seven signals connected to the external world:
