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. The serial interface is in 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 succes-
sively. 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.
