Current Sense Multiplexer
There is a current sense multiplexer implemented in the SPOC - BTS6460SF that routes the sense current of the
selected channel to the diagnosis pin IS. The channel is selected via SPI register DCR.MUX. The sense current
also can be disabled by SPI register DCR.MUX. For details on timing of the current sense multiplexer, please refer
