Transceiver state machine

When operating in transceiver mode the 'RF transmission' state machine is:

Idle state of the transceiver: by default the transceiver is waiting for

incoming data on the serial link and for incoming radio frame on the radio

link. The serial link has a higher priority than the radio link (if a radio frame

is demodulated meanwhile some characters are detected on the serial link,

the radio frame will be discarded and the serial incoming data will be

processed).

Processing incoming serial data: the incoming serial data are internally

buffered. The buffered data are sent on a radio frame (the RF modulation is

started) when at least one data is available and the preambule + synchro has

been sent on the radio

Processing incoming radio frame: the valid data are extracted from the

incoming radio frame and internally buffered. The buffered data are sent on

the fly to the serial module output. The internal buffer is limited to 64 bytes.
