Protection Operations
The status of a nonvolatile protection bit for a given block or group of blocks can be
read by issuing a READ NONVOLATILE MODIFY PROTECTION BIT command, along
with the block address.
The nonvolatile protection bits are erased simultaneously by issuing a CLEAR ALL
NONVOLATILE PROTECTION BITS (80/30h) command. No specific block address is re-
quired. If the nonvolatile protection bit lock bit is set to 0, the command fails.
