Boot Sector/Sector Block Protection and Unprotection
Note: For the following discussion, the term sector applies to both boot sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are protected or unprotected at the same time (see
Table
The hardware sector protection feature disables both program and erase operations in any sector. The
hardware sector unprotection feature re-enables both program and erase operations in previously protected
sectors. Sector protection/unprotection can be implemented via two methods.
Table 8.6 S29JL064J Boot Sector/Sector Block Addresses for Protection/Unprotection (Sheet 1 of 2)
8.6).
