14 / 48 page FLASH MEMORY K8D6x16UTM / K8D6x16UBM Revision 1.5 March 2005 14 COMMAND DEFINITIONS The K8D6316U operates by selecting and executing its operational modes. Each operational mode has its own command set. In order to select a certain mode, a proper command with specific address and data sequences must be written into the command reg- ister. Writing incorrect information which include address and data or writing an improper command will reset the device to the read mode. The defined valid register command sequences are stated in Table 8. Note that Erase Suspend (B0H) and Erase Resume (30H) commands are valid only while the Block Erase Operation is in progress. Table 8.
