The Timer/Counter1 incorporates a Fault Protection unit that can disable the PWM output pins, if
an external event is triggered. The external signal indicating an event can be applied via the
external interrupt INT0 pin or alternatively, via the analog-comparator unit. The Fault Protection
unit is illustrated by the block diagram shown in
that are not directly a part of the Fault Protection unit are gray shaded.
