Hi Russell,

You are right, all I want to do is bypass the next check because *if*
the PPIs can be configured, then any combination is valid (edge 
raising/falling, level low/high). In real systems, PPIs tend to be
configured with active level low. That falls the existing check.

If I understood more your thoughts on improving the comment then I can
try to come up with a better version.

Best regards,
Liviu
