Comments

This BCALL starts at the last Flash application page and works backwards until it finds a deleted or invalid application before the end of the list. If there is one, it returns NC.

"Invalid" counts as not having 800Fh or 000Fh at the beginning, zero for the number of pages, or not in the certificate.
