The WREN command sets the Write Enable Latch (WEL) bit. The WEL bit is cleared to 0 (disables writes) during power-up, hardware reset, or after the device completes the following commands: Reset Page Program (PP or 4PP) Parameter 4-kB Erase (P4E or 4P4E) Sector Erase (SE or 4SE) Bulk Erase (BE) Write Disable (WRDI) Write Registers (WRR) Write Any Register (WRAR) OTP Byte Programming (OTPP) Advanced Sector Protection Register Program (ASPP) Persistent Protection Bit Program (PPBP) Persistent Protection Bit Erase (PPBE) Password Program (PASSP) Program Non-Volatile Data Learning Register (PNVDLR) 9.3 Block Protection The Block Protect bits (Status Register bits BP2, BP1, BP0) in combination with the Configuration Register TBPROT_O bit can be used to protect an address range of the main flash array from program and erase operations. The size of the range is determined by the value of the BP bits and the upper or lower starting point of the range is selected by the TBPROT_O bit of the Configuration Register (CR1NV[5]).
