10 / 18 page X24F064/032/016 10 Block Lock Bits The Block Lock Bits BL0 and BL1 determine which blocks of the memory are write-protected: Table 1. Block Lock Bits 6686 FRM T02 BL1 BL0 Array Locked 0 0 None 0 1 Upper 1/4 1 0 Upper 1/2 1 1 Full Array (WPR not included) Programmable Hardware Program Protect The Program Protect (PP) pin and the Program Protect Enable (PPEN) bit in the Program Protect Register control the programmable hardware program protect feature. Hardware program protection is enabled when the PP pin and the PPEN bit are both HIGH, and disabled when either the PP pin is LOW or the PPEN bit is LOW. When the chip is hardware program- protected, nonvolatile programming is disabled, including the Program Protect Register, the BL bits and the PPEN bit itself, as well as to Block Locked sections in the memory array. Only the sections of the memory array that are not Block Locked can be written. Note that since the PPEN bit is program-protected, it cannot be changed back to a LOW state, and program protec- tion is disabled as long as the PP pin is held HIGH. Table 2 defines the program protection status for each state of PPEN and PP. Table 2.
