CC1101 Carrier Sense and Frequency Offset in Synchronous Serial RX mode

Other Parts Discussed in Thread: CC1101

Hello.

I am trying to operate a CC1101 in synchronous serial RX mode, without preamble or sync word detection using an MSP430. I was wondering, is it possible for the CC1101 to use one of the GPIO pins as 'Carrier Sense detect?' The way I see it, two of the GPIO pins (say GPIO0 and GPIO2) are used up for the two wire interface for RX. I'm not sure if the GPIO1 (or RF_MISO) line can be used for carrier sense gate.

Also, does the frequency offset compensation register 'FREQEST' work in such a case?

Thank You.
