General-purpose fuse bits
Erase All operation
Region lock bits
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
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 pro-
grammed with a 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 bit LOCKE has been written to 1 in FCR, the interrupt
line rises.
When the command is complete, the bit FRDY bit in the Flash Status Register (FSR) is set. If an
interrupt has been enabled by setting the bit FRDY in FCR, the interrupt line of the flash control-
ler is set. Two errors can be detected in the FSR register after issuing the command:
The flash block has p pages, and these pages are grouped into 16 lock regions, each region
containing p/16 pages. Each region has a dedicated lock bit preventing writing and erasing
pages in the region. After production, the device may have some regions locked. These locked
regions are reserved for a boot or default application. Locked regions can be unlocked to be
erased and then programmed with another application or other data.
To lock or unlock a region, the commands Lock Region Containing Page (LP) and Unlock
Region Containing Page (UP) are provided. Writing one of these commands, together with the
number of the page whose region should be locked/unlocked, performs the desired operation.
One error can be detected in the FSR register after issuing the command:
The lock bits are implemented using the lowest 16 general-purpose fuse bits. This means that
lock bits can also be set/cleared using the commands for writing/erasing general-purpose fuse
bits, see chapter 12.6. The general-purpose bit being in an erased (1) state means that the
region is unlocked.
The lowermost pages in the Flash can additionally be protected by the BOOTPROT fuses, see
Section
Each flash block has a number of general-purpose fuse bits that the application programmer can
use freely. The fuse bits can be written and erased using dedicated commands, and read

command must be executed previously to unlock the corresponding lock regions.
