Digital Audio interface
LISA-U100, LISA-U110 and LISA-U200-00S modules versions do not support digital audio interface.
LISA-U120 and LISA-U130 modules provide one bidirectional 4-wire I
2
S digital audio interface, while all LISA-U2
series modules versions except LISA-U200-00S provide two bidirectional 4-wire I
2
S digital audio interfaces for
connecting to remote digital audio devices.
LISA-U modules can act as an I
2
S master or I
2
S slave. In master mode the word alignment and clock signals of the
I
2
S digital audio interface are generated by the module. In slave mode these signal must be generated by the
remote device.
Table 46 lists the signals related to digital audio functions.
