of the timer clock, that is, the timer is always advanced by at least one before the
processor can read the counter value. The interrupt flags are updated three processor
cycles after the processor clock has started. During these cycles, the processor executes
instructions, but the interrupt condition is not readable, and the interrupt routine has not
started yet.
During asynchronous operation, the synchronization of the interrupt flags for the
asynchronous timer takes three processor cycles plus one timer cycle. The timer is
therefore advanced by at least one before the processor can read the timer value causing
the setting of the interrupt flag. The output compare pin is changed on the timer clock and
is not synchronized to the processor clock.
