On the first initialization or after a module reset following any frame error, the receiver module asserts and releases the receiver core reset bit (RX_MAIN_CTRL.CORE_RSTRX_MASTER_CTRL.CORE_RST) prior to any other initialization. Once the receiver module is initialized, the following steps are executed:
At this point the receiver is ready to receive any incoming frames. Software can now either poll on the RX_EVT_STS register for various conditions. For example, when the RX_EVT_STS.FRAME_DONE and no other flags are set, the receiver has successfully received a frame without error.
Next, the application configures the various features such as the ping and frame watchdogs, DMA, external triggering, and so on. These features are described in subsequent sections. The receiver module is now ready to synchronize with the transmitter then begin reception. The synchronization sequence is described in Section 12.4.5.5.1.
