plane may be performed even while program or erase functions are being executed in the other
memory plane.
One EFC is embedded in the AT91SAM7XC256/128 to control the single plane of 256/128
KBytes.

Lock Regions
8.5.3.1
AT91SAM7XC512
Two Embedded Flash Controllers each manage 16 lock bits to protect 16 regions of the flash
against inadvertent flash erasing or programming commands. The AT91SAM7XC512 contains
32 lock regions and each lock region contains 64 pages of 256 bytes. Each lock region has a
size of 16 Kbytes.
If a locked-region’s erase or program command occurs, the command is aborted and the EFC
trigs an interrupt.
The 32 NVM bits are software programmable through both of the EFC User Interfaces. The com-
mand “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.
8.5.3.2
AT91SAM7XC256
The Embedded Flash Controller manages 16 lock bits to protect 16 regions of the flash against
inadvertent flash erasing or programming commands. The AT91SAM7XC256 contains 16 lock
regions and each lock region contains 64 pages of 256 bytes. Each lock region has a size of 16
Kbytes.
If a locked-region’s erase or program command occurs, the command is aborted and the EFC
trigs an interrupt.
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.
8.5.3.3
AT91SAM7XC128
The Embedded Flash Controller manages 8 lock bits to protect 8 regions of the flash against
inadvertent flash erasing or programming commands. The AT91SAM7XC128 contains 8 lock
regions and each lock region contains 64 pages of 256 bytes. Each lock region has a size of 16
Kbytes.
If a locked-region’s erase or program command occurs, the command is aborted and the EFC
trigs an interrupt.
The 8 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.
8.5.4
Security Bit Feature
The AT91SAM7XC512/256/128 features a security bit, based on a specific NVM-Bit. When the
security is enabled, any access to the Flash, either through the ICE interface or through the Fast
