RX GO, from TRM, page 114 -
RX GO Start Receive. Setting this bit causes the device to transition to receive mode. If necessary, the crys-
tal oscillator and synthesizerstart automatically after this bit is set. Firmware must never clear this bit.
This bit must not be set until after it self clears. The recommended method to exit receive mode when
an error has occurred is to force END STATE and then dummy read all RX_COUNT_ADR bytes from
RX_BUFFER_ADR or poll RSSI_ADR.SOP (bit 7) until set. See “XACT_CFG_ADR” on page 124
and “RX_ABORT_ADR”on page 144for description.
