repeatedly counts up to the value set in the CR01.
Timer/counter 0 performs compare operations in which the value set in compare registers (CR00, CR01) are compared with
If the count value of TM0 matches the preset CR0n (n = 0, 1) value as the result of the count operation, a match signal is sent
After a match with the CR01 value, the TM0 count value can be cleared, and the timer functions as an interval timer that
