COMMAND DEFINITIONS Device operations are selected by writing specific address and data sequences into the command register. Writing incorrect address and data values or writing them in the improper sequence will reset the device to the read mode. Table 1 ...
Page 8
READ/RESET COMMAND The read or reset operation is initiated by writing the read/reset command sequence into the command reg- ister. Microprocessor read cycles retrieve array data. The device remains enabled for reads until the command register contents are altered. If ...
