MTIM Operation Example
This section shows an example of the MTIM operation as the counter reaches a matching value from the
modulo register.
Figure 11-7. MTIM Counter Overflow Example
In the example of Figure 11-7, the selected clock source could be any of the four possible choices. The
prescaler is set to PS = %0010 or divide-by-4. The modulo value in the MTIMMOD register is set to $AA.
When the counter, MTIMCNT, reaches the modulo value of $AA, the counter overflows to $00 and
continues counting. The timer overflow flag, TOF, sets when the counter value changes from $AA to $00.
An MTIM overflow interrupt is generated when TOF is set, if TOIE = 1.
