Note: 1. STTDLY is set to 0. In this example, SSC_THR is loaded twice. FSDEN value has no effect on the transmis-
sion. SyncData cannot be output in continuous mode.

43.7.8 Loop Mode
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.
43.7.9 Interrupt
Most bits in SSC_SR have a corresponding bit in interrupt management registers.
The SSC 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) These registers enable and disable,
respectively, 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 interrupt
controller.
