Timer Interrupts
The capture/compare timer can generate the following interrupts:
Input capture interrupt
Output compare interrupt
Timer overflow interrupt
Setting the I bit in the condition code register disables timer interrupts.
Input C apture
Interrupt
An input capture interrupt request occurs if the input capture flag, ICF,
becomes set while the input capture interrupt enable bit, ICIE, is also set.
ICF is in the timer status register, and ICIE is in the timer control register.
Output C ompare
Interrupt
An output compare interrupt request occurs if the output compare flag,
OCF, becomes set while the output compare interrupt enable bit, OCIE,
is also set. OCF is in the timer status register, and OCIE is in the timer
control register.
