TR_
CMD
Normally the signals in this register are generated by the layer 1 state machine. If the
internal layer 1 state machine is disabled (bit L1SW in TR_CONF = ’1’) this register can
be written by the microcontroller.

0: Transceiver in operational mode
1: Transceiver in power down mode. From the analog part only the level detector is
LP_A
The setting of this bit corresponds to the C/I command ARL.
0: Analog loop is open
1: Analog loop is closed
