This section shows an example of the MTIM operation as the counter reaches a matching value from the
modulo register.
In the example of
prescaler is set to PS = %0010 or divide-by-4. The modulo value in the
When the counter,
continues counting. The timer overflow flag, TOF, sets when the counter value changes from 0xAA to
0x00. An MTIM overflow interrupt is generated when TOF is set, if TOIE = 1.
