12.10 Fault Protection Unit
The Timer/Counter1 incorporates a Fault Protection unit, which can be set to disable the PWM
output pins when 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 in Figure 12-19. The elements of the block diagram that are not
directly a part of the Fault Protection unit are gray shaded.
Figure 12-19.
Fault Protection Unit Block Diagram
Fault Protection mode is enabled by setting the Fault Protection Enable (FPEN1) bit and trig-
gered by a change in logic level at external interrupt pin (INT0). Alternatively, fault protection
mode can be triggered by the Analog Comparator Output (ACO).
When Fault Protection is triggered, the COM1x bits are cleared, Output Comparators are discon-
nected from the PWM output pins and PORTB register bits are connected to the PWM output
