72 / 80 page ![]() Extended Memory Block M29DW641F 72/80 C.2 Customer Lockable section of the Extended Block The device is delivered with the second section of the Extended Block "Customer Lockable": bits DQ7 and DQ6 are set to '1' and '0' respectively. It is up to the customer to program and protect this section of the Extended Block but care must be taken because the protection is not reversible. There are three ways of protecting this section: ● Issue the Enter Extended Block command to place the device in Extended Block mode, then use the In-System Technique with RP either at VIH or at VID. Refer to Section D.2: In-system technique in Appendix D: High voltage Block Protection, and to the corresponding flowcharts Figure 24 and Figure 25 for a detailed explanation of the technique). ● Issue the Enter Extended Block command to place the device in Extended Block mode, then use the Programmer Technique. Refer to Section D.1: Programmer technique in Appendix D: High voltage Block Protection, and to the corresponding flowcharts Figure 22 and Figure 23 for a detailed explanation of the technique). ● Issue a Set Extended Block Protection bit command to program the Extended Block Protection bit to ‘1’ thus preventing the second section of the Extended Block from being programmed. Bit DQ6 of the Extended Block Protection indicator is automatically set to '1' to indicate that the second section of the Extended Block is Customer Locked. Once the Extended Block is programmed and protected, the Exit Extended Block command must be issued to exit the Extended Block mode and return the device to Read mode. Table 35.
