Start Address + Flash size -1
The embedded Flash size, the page size, the lock regions organization and GPNVM bits defini-
tion are described in the product definition section. The Enhanced Embedded Flash Controller
(EEFC) returns a descriptor of the Flash controlled after a get descriptor command issued by the
application (see
• One write buffer that manages page programming. The write buffer size is equal to the page
• Several lock bits used to protect write/erase operation on several pages (lock region). A lock
• Several bits that may be set and cleared through the Enhanced Embedded Flash Controller
size. This buffer is write-only and accessible all along the 1 MByte address space, so that
each word can be written to its final address.
