Hi,

L9779WD-SPI is an excellent IC for automotive, with the exception of it's datasheet.

SPI communication section of datasheet confused me and other engineers of our section!

We read 0xFFFF in the first write/access to registers, a data on then next write/access, and 0x0000 on others write/access.

An example code will be appreciated.

Best Regards,

Ahmad

    I found this: one 16bit SPI frame for writing to L9779 and tow 16bit SPI frame for reading from L9779.

    You can't find it on the datasheet!
