Commands Instructions and Commands The Command Interface (C.I.) latches commands written to the memory. Instructions are made up from one or more commands to perform Read Array/Reset, Read Electronic Signature, Block Erase, Chip Erase, Program, Block Erase Suspend and Erase Resume. Commands are made of ad- dress and data sequences. Addresses are latched on the falling edge of W or E and data is latched on the rising of W or E. The instructions require from 1 to 6 cycles, the first or first three of which are always write operations used to initiate the com- mand. They are followed by either further write cycles to confirm the first command or execute the command immediately. Command sequencing must be followed exactly. Any invalid combination of commands will reset the device to Read Array. The increased number of cycles has been chosen to assure maximum data security. Commands are initialised by two preceding coded cycles which unlock the Command Interface. In addition, for Erase, command confirmation is again preceeded by the two coded cycles. P/E.C. status is indicated during command execu- tion by Data Polling on DQ7, detection of Toggle on DQ6, or Error on DQ5 and Erase Timer DQ3 bits. Any read attempt during Program or Erase com- mand execution will automatically output those four bits. The P/E.C. automatically sets bits DQ3, DQ5, DQ6 and DQ7. Other bits (DQ0, DQ1, DQ2 and DQ4) are reserved for future use and should be masked. 7/31 M29F040 |
