TLE 6244X

1.6 SPI Interface

The serial SPI interface establishes a communication link between TLE6244X and the systems mi-

crocontroller. TLE6244X always operates in slave mode whereas the controller provides the mas-

ter function. The maximum baud rate is 5 MBaud.

The TLE6244X is selected by the SPI master by an active slave select signal at SS and by the first

two bits of the SPI instruction.SI is the data input (Slave In), SO the data output (Slave Out). Via

SCK (Serial Clock Input) the SPI clock is provided by the master.

In case of inactive slave select signal (High) the data output SO goes into tristate.
