BLOCKERASE
The Erase operationcanerase ona block (8K Byte) basis. Block address loading is accomplishedintwo
cycles initiatedby anErase Setupcommand(60h). Only address A13 toA21 is validwhile A9 toA12 is
ignored. TheaddressesoftheblocktobeerasedtoFFh. TheEraseConfirmcommand(D0h) followingthe
block address loading initiates the internal erasing process. This two-stepsequence of setupfollowedby
