seсurity bit in AT91SAM7S

Hi, i have a question about an access restriction of writing to on-chip flash after setting the security bit. Can i program the flash through an EFC after setting the security bit?

    Setting the security bit disables any access to the flash through external interfaces (ICE/FFP/...). The type of access (read or write) is not relevant.

    Internal access to the flash is not affected.
