I am using the low side driver chip TLE9104SH for my company's project, the SPI is emulated by GPIO. While testing timing, the TLE9104SH no reply at all(always high, VDD is 5V, VIO is 3.3V).
The oscilloscope picture 1, yellow line is CS, pink line is MOSI, light blue line is CLK, the always high line is MISO.
Can any one provide demo code, right timing diagram, or application note about TLE9104SH?
The datasheet is too simple to solve or analyze the problem.
Thanks a lot.

Hi Team,
Any application notes for TLE9104 available ? ; I have the switch used in my design task. The MISO valid time seems to be 2.4 us which fails against the datasheet value

Hi Team,
Any application notes for TLE9104 available ? ; I have the switch used in my design task. The MISO valid time seems to be 2.4 us which fails against the datasheet value
Also please confirm on the read frame in datasheet;
We write on MOSI & validated MOSI in SPI analyser
but when I give a read command using MOSI to read the config register, we are unable to get the set register value in MISO. Any suggestion would help.
