DIGITAL AUDIO INTERFACES

Audio data is transferred to and from the WM8580 via the digital audio interfaces. There are two

receive audio interfaces and two transmit audio interfaces. The digital routing options for these

interfaces are described on page 22. Control of the audio interfaces is described below.

MASTER AND SLAVE MODES

The audio interfaces require both a left-right-clock (LRCLK) and a bit-clock (BCLK). These can be

supplied externally (slave mode) or they can be generated internally (master mode). When in master

mode, the BCLKs and LRCLKs for an interface are output on the corresponding BCLK and LRCLK

pins. By default, all interfaces operate in slave mode, but can operate in master mode by setting the

PAIFTXMS, PAIFRXMS and SAIFMS register bits. In Hardware Control Mode, the PAIF Transmitter

can operate in master mode by setting the SDI pin.
