Table 41 Audio Interface Control
AUDIO INTERFACE CONTROL
The register bits controlling audio format, word length and master / slave mode are summarised
below. Each audio interface can be controlled individually.
Register bit MS selects audio interface operation in master or slave mode. In Master mode BCLK,
and FRAME are outputs. The frequency of BCLK and FRAME in master mode are controlled with
BCLKDIV. These are divided down versions of master clock. This may result in short BCLK pulses
at the end of a frame if there is a non-integer ratio of BCLKs to FRAME clocks.
