SPI Signal Description
CS - Chip Select. The system microcontroller selects the TLE6240GP by means of the CS pin. Whenever the pin
is in a logic low state, data can be transferred from the µC and vice versa.
•
•
To avoid any false clocking the serial clock input pin SCLK should be logic low state during high to low transition
of CS. When CS is in a logic high state, any signals at the SCLK and SI pins are ignored and SO is forced into a
high impedance state.
SCLK - Serial Clock. The system clock pin clocks the internal shift register of the TLE6240GP. The serial input
(SI) accepts data into the input shift register on the falling edge of SCLK while the serial output (SO) shifts
Data Sheet
CS High to Low Transition:
– diagnostic status information is transferred from the power outputs into the shift register
– serial input data can be clocked in from then on
– SO changes from high impedance state to logic high or low state corresponding to the SO bits
CS Low to High Transition:
– transfer of SI bits from shift register into output buffers
