In Example 8.2, we used the polling method to check for the arrival of edges. Write a program that uses the interrupt-driven approach to measure the period of an unknown signal. There will be two interrupts related to the PT0 active edges and zero or more TCNT over flow interrupts to be dealt with.

Example 8.2

Period measurement. Use the input-capture channel 0 to measure the period of an unknown signal. The period is known to be shorter than 128 ms. Assume that the E-clock frequency is 24 MHz. Use the number of clock cycles as the unit of the period.
