9.0 COMMAND DEFINITIONS

The K8P5616UZB operates by selecting and executing its operational modes. Each operational mode has its own command set. In order to select a cer-

tain mode, a proper command with specific address and data sequences must be written into the command register. 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 5.
