program data. Programming is initiated at the last rising edge of the
serial clock during program data transfer. The BUSY pin is driven
high during program operation. Programming is completed within 10

gram verify command after executing the program command.
In the case of failure in the verification, the user must repeat-
edly execute the program command until the pass in the veri-
fication. Refer to Figure 12 for the programming flowchart.
