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 an
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. The serial
interface is in the reset state if the level on pin CS = Low.
During a RX operation, the user can read the received bytes in the TX/RX data buffer
successively.
During a TX operation the user can write the bytes in the TX/RX data buffer successively. An
echo of the command and the TX data bytes are provided for the microcontroller on pin
SDO_TMDO.
The control and status registers can be read individually or successively.
