23.3.3.1.7 CMD_RX_TEST: Receiver Test Command
Command ID number: 0x0807
CMD_RX_TEST is a radio operation command used to set the receiver in infinite RX mode for test
purposes.
The sync word programmed in the receiver is given in the LSBs of syncWord. If config.bNoSync is 1, the
correlation thresholds for sync search are set to the maximum value to avoid getting sync. The thresholds
are restored after the command ends. If config.bEnaFifo is 0, the modem FIFO is not enabled so that
received bits are not stored. If config.bEnaFifo is 1, the modem FIFO is enabled, but data is not read out;
this must then be done by the application. After sync and before the end trigger, the radio CPU does not
access the modem registers, so that accesses directly from the system CPU to the FIFO registers can be
safely done.
If pktConfig.bFsOn is 1, the synthesizer is turned off (corresponding to CMD_FS_OFF; see
Section 23.3.3.1.6) after the operation is done; otherwise the synthesizer is left on.
A trigger to end the operation is set up by endTrigger and endTime (see
that is defined by this parameter occurs, the radio operation ends.
The operation ends by one of the causes listed in
