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 Figures 5-30 and 5-31.
