RX Indicator
Frame Type: (0x90)
When the module receives an RF packet, it is sent out the UART using this message type.
Example: Example: In the above example, a device with a 64-bit address of 0x0013A200
40522BAA sends a unicast data transmission to a remote device with payload "RxData". If AO=0
on the receiving device, it would send the above frame out its serial interface.
