The configuration of the transceiver takes place via a 4-wire serial interface (CS, SCK,
SDI_TMDI, SDO_TMDO) and is organized in 8-bit units. The configuration is initiated with a 8-bit
command. While shifting the command into pin SDI_TMDI, the number of bytes in the TX/RX
data buffer are available on pin SDO_TMDO. The read and write commands are followed by one
or more 8-bit data units. Each 8-bit data transmission begins with the MSB.
During a RX operation the user can read the received bytes in the TX/RX data buffer
successively.
