Comments
This B_CALL deletes any applications which do not have 800Fh at the beginning by writing a zero to 4000h on the base page (and possibly any subpages). It also may check the app presence bitmap in the certificate.
Its purpose is likely to delete incomplete Flash applications received through the link port or USB. It is used as an error handler in some of the link routines.
