In case of over current as well as over temperature, the current sense signal of the affected channel is switched
off. To distinguish between over temperature and over load, the SPI diagnosis word can be used. Whereas the
over load flag is cleared every time the diagnosis is transmitted, the over temperature flag is cleared by a dedicated
SPI command (HWCR.CTL).
Details about timings between the current sense signal
be found in
