Flash Configuration Summary
If a locked-region’s erase or program command occurs, the command is aborted and the
LOCKE bit in the MC_FSR register rises and the interrupt line rises if the LOCKE bit has been
written at 1 in the MC_FMR register.
The 16 NVM bits are software programmable through the EFC User Interface. The command
“Set Lock Bit” enables the protection. The command “Clear Lock Bit” unlocks the lock region.
Asserting the ERASE pin clears the lock bits, thus unlocking the entire Flash.
The Embedded Flash Controller manages 8 lock bits to protect 8 regions of the flash against
inadvertent flash erasing or programming commands. The AT91SAM7S321/32 contains 8 lock
regions and each lock region contains 32 pages of 128 bytes. Each lock region has a size of 4
Kbytes.
If a locked-region’s erase or program command occurs, the command is aborted and the
LOCKE bit in the MC_FSR register rises and the interrupt line rises if the LOCKE bit has been
written at 1 in the MC_FMR register.

The Embedded Flash Controller manages 8 lock bits to protect 8 regions of the flash against
inadvertent flash erasing or programming commands. The AT91SAM7S161/16 contains 8 lock
regions and each lock region contains 32 pages of 64 bytes. Each lock region has a size of 2
Kbytes.
