Figure 14-2. Timer/Counter 1 Synchronization Register Block Diagram.
Timer/Counter1 and the prescaler allow running the CPU from any clock source while the pres-
caler is operating on the fast 64 MHz (or 32 MHz in Low Speed Mode) PCK clock in the
asynchronous mode.
Note that the system clock frequency must be lower than one third of the PCK frequency. The
synchronization mechanism of the asynchronous Timer/Counter1 needs at least two edges of
the PCK when the system clock is high. If the frequency of the system clock is too high, it is a
risk that data or control values are lost.
