least one before the processor can read the counter value. After wake-up, the MCU
is halted for four cycles, it executes the interrupt routine, and resumes execution
from the instruction following SLEEP.
•
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 1 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.
