L9301

SPI

The SPI interface is used to configure the device, control the output and read the diagnostic

and output status registers.

Every time a bit in one of the SPI registers is set by the L9301 (for example when an error is

detected) it will not be reset until the corresponding registers have been wrote to 0 by SPI.

The bit will not be reset if an SPI error occurs during access to register by the µC or while

L9301 sends the content of the register as an answer.
