Hi:
I'm having problem talking to MC33978.
The MCU is STM32F745.
The SPI check command works, returns MISO = "0x00123456"
But other commands return wrong data.
Switch status command 0x3E000000, returns MISO = 0x3FBADBAD
Tristate SP disable 0x05000000, returns MISO = 0x07BADBAD
Fault Status Reg command 0x42000000, returns MISO = 0x23800000.
SPI communication setup in the STM32F MCU project:
Clock polarity = high
Clock phase = first edge
What is the meaning of "BADBAD" in MISO?
Why I'm getting this response?
Thank you
Shirley
