The power transistors are switched on and off with a dedicated slope via the IN bits of the serial peripheral interface
SPI or by the dedicated input pins and the input mode which is also programmed by SPI. The switching times
and
consumption is reduced to a minimum. To switch the channel on again, OFF mode must be programmed and a
wake up time

In Input Mode, a high signal at the input pin is equivalent to a SPI ON command and a low signal to SPI OFF
command respectively. Please refer to
