-/** \addtogroup ssc_module Working with SSC
- * \ingroup peripherals_module
- * The SSC driver provides the interface to configure and use the SSC
- * peripheral.
- *
- * !Usage
- *
- * -# Enable the SSC interface pins.
- * -# Configure the SSC to operate at a specific frequency by calling
- * SSC_Configure(). This function enables the peripheral clock of the SSC,
- * but not its PIOs.
- * -# Configure the transmitter and/or the receiver using the
- * SSC_ConfigureTransmitter() and SSC_ConfigureEmitter() functions.
- * -# Enable the PIOs or the transmitter and/or the received.
- * -# Enable the transmitter and/or the receiver using SSC_EnableTransmitter()
- * and SSC_EnableReceiver()
- * -# Send data through the transmitter using SSC_Write()
- * -# Receive data from the receiver using SSC_Read()
- * -# Disable the transmitter and/or the receiver using SSC_DisableTransmitter()
- * and SSC_DisableReceiver()
- *
- * For more accurate information, please look at the SSC section of the
- * Datasheet.
