Serial Synchronous Controller
Provides serial synchronous communication links used in audio and telecom applications
Contains an independent receiver and transmitter and a common clock divider
Offers a configurable frame sync and data length
Receiver and transmitter can be programmed to start automatically or on detection of
different event on the frame sync signal
Receiver and transmitter include a data signal, a clock signal and a frame synchronization
signal
