Figure 31-14. Receive Frame Format in Continuous Mode
Note:
The receiver can be programmed to receive transmissions from the transmitter. This is done by
setting the Loop Mode (LOOP) bit in SSC_RFMR. In this case, RD is connected to TD, RF is
connected to TF and RK is connected to TK.
Most bits in SSC_SR have a corresponding bit in interrupt management registers.
The SSC Controller can be programmed to generate an interrupt when it detects an event. The
Interrupt is controlled by writing SSC_IER (Interrupt Enable Register) and SSC_IDR (Interrupt
Disable Register), which respectively enable and disable the corresponding interrupt by setting
and clearing the corresponding bit in SSC_IMR (Interrupt Mask Register), which controls the
generation of interrupts by asserting the SSC interrupt line connected to the AIC.

The SSC can support several serial communication modes used in audio or high speed serial
links. Some standard applications are shown in the following figures. All serial link applications
supported by the SSC are not listed here.
