The SPI is a Serial Peripheral Interface with 4 digital pins and a 16-bit shift register. The SPI is used to configure
and program the device, turn on and off channels and to read detailed diagnostic information.

CS - Chip Select. The system microcontroller selects the TLE6288R by means of the CS pin. Whenever the pin is
in a logic low state, data can be transferred from the µC and from the TLE6288R to the µC.

To avoid any false clocking the serial clock input pin SCLK should be logic high state (if CLKProg = L; low state if
CLKProg = H) during high to low transition of CS.
SCLK - Serial Clock. The serial clock pin clocks the internal SPI shift register of the TLE6288R. The serial input
(SI) accepts data into the input SPI shift register on the rising edge of SCLK (if CLKProg = L; falling edge if
CLKProg = H) while the serial output (SO) shifts diagnostic information out of the SPI shift register on the falling
Data Sheet
CS = H: Any signals at the SCLK and SI pins are ignored and SO is forced into a high impedance state.
CS = H → L:
– diagnostic information is transferred from the diagnosis register into the SPI shift register
– serial input data can be clocked into the SPI shift register from then on
– SO changes from high impedance state to logic high or low state corresponding to the SO bits
CS = L: SPI is working like a shift register. With each clock signal the state of the SI is read into the SPI shift-
register and one diagnosis bit is written out of SO.
CS = L → H:
– transfer of SI bits from SPI shift register into the internal logic registers
– reset of diagnosis register if sent command was valid
