① Hardware error bit is set if the voltage at SATFDX is above the specified values. The hardware error bit is
also set if the pull-down current is above the specified value. The affected interfaces will be switched off.
② Will be activated at 0.5V above the output voltage SATFDX. After a debouncing time of 512µs, the channel
will be switched off (see table in chapter 5.2.5.5
