The control and status registers can be read individually or successively.
The control registers can be written individually or successively. An echo of the command and
the data bytes are provided for the microcontroller on pin SDO_TMDO.
If AVCC_EN in control register 1 is 0, the input level on pin PWR_ON is low and on the key
inputs Tn is high, the OFF command sets the transceiver in the OFF mode.
