ENHANCED SOFTWARE WRITE

PROTECTION MODE

When the EWPM bit is set to logic ‘1’, the 24CSM01 is

configured for a versatile software write protection

scheme by segmenting the EEPROM array into eight

independent 128-Kbit zones (see Table 6-2). Each of

the eight zones can be write-protected by programming

the corresponding bit in the Configuration register. The

protection behavior can be made permanent by locking

the Configuration register (see Section 9.5 “Locking

the Configuration Register” for additional details).

Note:

Enhanced software write protection does

not affect write operations to the Security

and Configuration registers.
