Address (1)
The BFC performs continuous burst reads. It is also possible to program page sizes from 16
bytes up to 1024 bytes. This is done by setting the appropriate value in the PAGES field of the
“Burst Flash Controller Mode Register” on page
of the BFC (Suspend). When the BFC is requested again, a new burst is started even though
the requested address is sequential to the previously requested address.
