5.30 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).
