Once the MCU is initialized, the main loop may be interrupted by the
input capture and the output compare interrupt service routines.
Figure 1-11. Software Flow Diagram
1.7 Input Capture
The input capture interrupt service routine is executed every time the
input capture timer channel detects an edge on the zero crossing input.
The input capture time is read from the timer channel. The average
period is calculated over two cycles. This value is used as criteria for
locking on the input line frequency. The minimum and maximum periods
are set up to lock from 30 Hz to 90 Hz. This will accommodate both 50-
and 60-Hz possibilities and up to 50 percent error in the clock frequency.
