Chapter 13 Modulo Timer (S08MTIMV1)
13.4.1
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 $AA to $00.
An MTIM overflow interrupt is generated when TOF is set, if TOIE = 1.
