Nr. Bytes in the TX/RX Data Buffer
The control registers can be written individually or successively. An echo of the com-
mand 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.

The delete IRQ command sets pin IRQ to low.

The three most significant bits of the command (Bit 5 to Bit 7) indicates the command
type. Bit 0 to Bit 4 describes the target address when reading or writing a control or sta-
tus register. In all other commands Bit 0 to Bit 4 have no effect and should be set to 0 for
compatibility reasons with future products.
