3.11.4 VDD - off Comparator
The VDD-off Comparator detects a disconnection of the VDD pin supply voltage. In this case, the TLE5011 is
supplied by the SCK, CLK and CS input pins via the ESD structures. It activates the STAT_VR bit.
The retriggerable analog monoflop is necessary because of the non-static signal of the CLK and SCK signals.
This comparator is also activated if spikes on CLK or SCK achieve the condition:
(VCLK - VDD) > VVDDoff or (VSCK - VDD) > VVDDoff
