33.4.1 Comparator Output Synchronization

The output from a comparator can be synchronized with Timer1 by setting the SYNC bit.

Once enabled, the comparator output is latched onto the falling edge of the Timer1 source clock. If a prescaler is used with Timer1, the comparator output is latched after the prescaling function. To prevent a Race condition, the comparator output is latched onto the falling edge of the Timer1 clock source and Timer1 increments on the rising edge of its clock source. See Figure 33-2 and Figure 19-1 for more information.
