Note:
The receiver can be programmed to receive transmissions from the transmitter. This is done by
setting the Loop Mode (LOOP) bit in RFMR. In this case, RX_DATA is connected to TX_DATA,
RX_FRAME_SYNC is connected to TX_FRAME_SYNC and RX_CLOCK is connected to
TX_CLOCK.
Most bits in 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 IER (Interrupt Enable Register) and IDR (Interrupt Disable Register) These
registers enable and disable, respectively, the corresponding interrupt by setting and clearing
the corresponding bit in IMR (Interrupt Mask Register), which controls the generation of inter-
rupts by asserting the SSC interrupt line connected to the interrupt controller.
