Spartan-3AN - Locking down a sector does not involve a sector erase

Description

Pg. 80 of ug333, the Spartan-3ANIn-System FlashUser Guide (v2.1), has the following sentence:

"The page address and byte address bits, which follow the Sector Address, specify any valid address location within the sector which is to be erased."

Is there an erase during a sector lockdown?

Solution

This is a typo. The last word should be changed from erased to protected or locked down; there is no erasing that occurs before or after a sector is locked down.
