After programming, the page can be locked to prevent miscellaneous write or erase sequences.
Locking is performed on a per-region basis, so locking a region locks all pages inside the region.
Additional protection is provided for the lowermost address space of the flash. This address
space is allocated for the Boot Loader, and is protected both by the lock bit(s) corresponding to
this address space, and the BOOTPROT[2:0] fuses.
Data to be written is stored in an internal buffer called the page buffer. The page buffer contains
w words. The page buffer wraps around within the internal memory area address space and
appears to be repeated by the number of pages in it. Writing of 8-bit and 16-bit data to the page
buffer is not allowed and may lead to unpredictable data corruption.
Data must be written to the page buffer before the programming command is written to the Flash
Command Register (FCMD). The sequence is as follows:
Reset the page buffer with the Clear Page Buffer command.
Fill the page buffer with the desired contents as described in Section 8.4.8 on page 81.
Programming starts as soon as the programming key and the programming command are
written to the Flash Command Register. The PAGEN field in the Flash Command Register
(FCMD) must contain the address of the page to write. PAGEN is automatically updated
when writing to the page buffer, but can also be written to directly. The FRDY bit in the Flash
Status Register (FSR) is automatically cleared when the page write operation starts.
When programming is completed, the FRDY bit in the Flash Status Register (FSR) is set. If
an interrupt was enabled by writing FCR.FRDY to one, an interrupt request is generated.
Two errors can be detected in the FSR register after a programming sequence:
Programming Error: A bad keyword and/or an invalid command have been written in the
FCMD register.
Lock Error: Can have two different causes:
– The page to be programmed belongs to a locked region. A command must be
executed to unlock the corresponding region before programming can start.
– A bus master without secure status attempted to program a page requiring secure
privileges.
8.5.2
Erase All Operation
The entire memory is erased if the Erase All command (EA) is written to the Flash Command
Register (FCMD). Erase All erases all bits in the flash array. The User page is not erased. All
flash memory locations, the general-purpose fuse bits, and the security bit are erased (reset to
0xFF) after an Erase All.
The EA command also ensures that all volatile memories, such as register file and RAMs, are
erased before the security bit is erased.
Erase All operation is allowed only if no regions are locked, and the BOOTPROT fuses are con-
figured with a BOOTPROT region size of 0. Thus, if at least one region is locked, the bit LOCKE
in FSR is set and the command is cancelled. If the LOCKE bit in FCR is one, an interrupt request
is set generated.
When the command is complete, the FRDY bit in the Flash Status Register (FSR) is set. If an
interrupt has been enabled by writing FCR.FRDY to one, an interrupt request is generated. Two
errors can be detected in the FSR register after issuing the command:
