Receive Mode
If over-the-air data is present at the RF receiver when the module is in Idle
Mode, it will transition to Receive Mode and start receiving packets. Once a
packet is received, it goes through a CRC (cyclic redundancy check) to
ensure that the data was transmitted correctly. If the CRC data bits on the
incoming packet are invalid, the packet is discarded. If the CRC is valid, the
packet is sent to the serial port via the DO pin. This process is shown in
Figure 6 below.
