Receiver Re-Synchronisation
/* Pseudo-code for the use of re-synchronising feature in the CMX980A */
/*
/* When using low data rate on the rx data serial port
/* alternate I & Q samples are transmitted.
/* If synchronisation is lost with the serial port by
/* missing a data word, then use the method below to
/* re-gain sync and identify the correct channel for
/* data received.
/*
/* It is assumed that the RxSampleSel bit has been set
/* to give the requred sample phasing
/* i.e. I before Q
