If the supply voltage drops below ±12.5 V, the UnderVoltage
Protection (UVP) circuit is
activated and the system will shut-down
correctly. If the internal clock is used, this
switch-off will be silent and without pop
noise. When the supply voltage rises above the
threshold level, the system is restarted
again after 100 ms. If the supply voltage exceeds
±33 V the OverVoltage
Protection (OVP) circuit is activated and the power stages will
shut-down. It is re-enabled as soon as the
supply voltage drops below the threshold level.
So in this case no timer of 100 ms is started
