16.8
16.8.1
If the compare match is selected for counter clear, TCNT is cleared at the last state in the cycle in
which the values of TCNT and TCOR match. TCNT updates the counter value at this last state.
Therefore, the counter frequency is obtained by the following formula.
16.8.2
If a counter clear signal is generated during the T
priority and the write is not performed as shown in figure 16.15.
f = φ / (N + 1 )
f:
φ: Operating frequency
N: TCOR value
