ADVANCE INFORMATION
operations
seven 64 Kbyte sectors (byte mode)
seven 32 Kword sectors (word mode)
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
Sectors can be locked in-system or via
programming equipment
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
