3.7.6 RX Telegram Handling

The reception of a telegram is performed in several phases within the ATA8210/15. After the initialization and start-up phase, the receiver checks for a valid RF signal, which results in a wake check OK (WCO). The next step is to search the start frame ID (SFID) pattern that marks the beginning of the payload (start of the telegram, SOT). The payload reception is terminated if an end of telegram (EOT) condition becomes true. The following figure gives an overview of the receive telegram-handling process.
