This register holds the high byte of the 16-bit program memory read/write/erase limit
address. The entire 16-bit access limit address value is calculated as 0xNN00 where NN is
replaced by contents of FLACL. A write to this register sets the Flash Access Limit. This reg-
ister can only be written once after any reset. Any subsequent writes are ignored until the
next reset.
