Functions
void	SSC_Configure (Ssc *ssc, uint32_t bitRate, uint32_t masterClock)
	Configures a SSC peripheral.If the divided clock is not used, the master clock frequency can be set to 0.
void	SSC_ConfigureTransmitter (Ssc *ssc, uint32_t tcmr, uint32_t tfmr)
	Configures the transmitter of a SSC peripheral.
void	SSC_ConfigureReceiver (Ssc *ssc, uint32_t rcmr, uint32_t rfmr)
	Configures the receiver of a SSC peripheral.
void	SSC_EnableTransmitter (Ssc *ssc)
	Enables the transmitter of a SSC peripheral.
void	SSC_DisableTransmitter (Ssc *ssc)
	Disables the transmitter of a SSC peripheral.
void	SSC_EnableReceiver (Ssc *ssc)
	Enables the receiver of a SSC peripheral.
void	SSC_DisableReceiver (Ssc *ssc)
	Disables the receiver of a SSC peripheral.
void	SSC_EnableInterrupts (Ssc *ssc, uint32_t sources)
	Enables one or more interrupt sources of a SSC peripheral.
void	SSC_DisableInterrupts (Ssc *ssc, uint32_t sources)
	Disables one or more interrupt sources of a SSC peripheral.
void	SSC_Write (Ssc *ssc, uint32_t frame)
	Sends one data frame through a SSC peripheral. If another frame is currently being sent, this function waits for the previous transfer to complete.
uint32_t	SSC_Read (Ssc *ssc)
	Waits until one frame is received on a SSC peripheral, and returns it.
uint8_t	SSC_IsRxReady (Ssc *ssc)
	Return 1 if one frame is received, 0 otherwise.

Detailed Description

Implementation of Synchronous Serial (SSC) controller.
