EEPROM (M95P08-I) Safety register

[1123]

Hi , 

I am using an M95P08-I SPI EEPROM . And I can now write/erase/program the EEPROM successfully. But I tried reading the Safety register format (RDCR) and found that the Power-up flag (PUF) bit and the Erase flag (ERF) bit were 1.
Aften  tried using the CLRSF instruction to clear the safe flag or the software reset instruction, but I reread the security register format  (the PUF bit and ERF bit) were still 1.

PS : Status register don't make any protection bit , only make Write enable latch (WEL) bit to 1 .

How should I deal with this problem ?? 

Thank you,
