The Synchronous Serial Controller (SSC) provides a synchronous communication link with
external devices. It supports many serial synchronous communication protocols generally used
in audio and telecom applications such as I2S, Short Frame Sync, Long Frame Sync, etc.
The SSC consists of a receiver, a transmitter, and a common clock divider. Both the receiver
and the transmitter interface with three signals:
• the TX_DATA/RX_DATA signal for data
• the TX_CLOCK/RX_CLOCK signal for the clock
• the TX_FRAME_SYNC/RX_FRAME_SYNC signal for the frame synchronization
The transfers can be programmed to start automatically or on different events detected on the
Frame Sync signal.
The SSC’s high-level of programmability and its two dedicated Peripheral DMA Controller chan-
nels of up to 32 bits permit a continuous high bit rate data transfer without processor
intervention.
Featuring connection to two Peripheral DMA Controller channels, the SSC permits interfacing
with low processor overhead to the following:
• CODEC’s in master or slave mode
• DAC through dedicated serial interface, particularly I2S
• Magnetic card reader
Provides serial synchronous communication links used in audio and telecom applications
Independent receiver and transmitter, common clock divider
Interfaced with two Peripheral DMA Controller channels to reduce processor overhead
Configurable frame sync and data length
Receiver and transmitter can be configured to start automatically or on detection of different
events on the frame sync signal
Receiver and transmitter include a data signal, a clock signal and a frame synchronization signal
