Write STATUS Register (WRSR)

The Write STATUS Register (WRSR) command writes

new values to the Configuration register. To execute a

Write STATUS Register operation, the host drives CE#

low, then sends the Write STATUS Register command

cycle (01H), two cycles of data, and then drives CE#

high. Values in the second data cycle will be accepted

by the device. See Figure 5-30 and Figure 5-31.
