Example when two capture registers are used (using overflow interrupt)
The TPnOVF0 and TPnOVF1 flags are set on the internal RAM by software.

Read the TPnOVF0 flag. If the TPnOVF0 flag is 1, clear it to 0.

Read the TPnOVF1 flag. If the TPnOVF1 flag is 1, clear it to 0 (the
TPnOVF0 flag is cleared in <4>, and the TPnOVF1 flag remains 1).
