10.5.4

Serial Synchronous Controller

• Provides serial synchronous communication links used in audio and telecom applications

(with CODECs in Master or Slave Modes, I2S, TDM Buses, Magnetic Card Reader, etc.)

• 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
