RcvClkSelI
If set to 1, the I-clock is used for the receiver clock.
Set to 0 indicates, that the Q-clock is used. I-clock and Q-clock are 90° phase
shifted to each other
6
RxAutoPD
If set to 1, the receiver circuit is automatically switched on before receiving and
switched off afterwards. This may be used to reduce current consumption.
If set to 0, the receiver is always activated.
