The SPOC - BTS6480SF is supplied by two supply voltages
switches. The
pins VDD and GND is recommended as shown in
There is a power-on reset function implemented for the
supply, all SPI registers are reset to their default values. The SPI interface including daisy chain function is active

Idle mode parameters are valid, when all channels are switched off, but the current sense multiplexer is not in

Note: A transition from operation to stand-by mode does not reset the SPI registers. So, if
