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, then the OFF command sets the transceiver in the OFF mode.
Figure 8-5.
The delete IRQ command sets pin IRQ to low.
Figure 8-6.
The three most significant bits of the command (bit 5 to bit 7) indicate the command type. Bit 0 to
bit 4 describe the target address when reading or writing a control or status register. In all other
commands bit 0 to bit 4 have no effect and should be set to “0” for compatibility with future
products.
