Example when two capture registers are used (without using overflow
interrupt)
The TPnOVF0 and TPnOVF1 flags are set on the internal RAM by software.

Read the overflow flag. If the overflow flag is 1, set only the TPnOVF1
flag to 1, and clear the overflow flag to 0.
Because the overflow flag is 1, the pulse width can be calculated by

Read the overflow flag. Because the overflow flag is cleared in <4>, 0
