WRITE Status Register Instruction (WRSR)

This instruction provides the ability to write the status register and select among several operating modes.

Several of the register bits must be set to a low ‘0’ if any of the other bits are written. The timing sequence

to write to the status register is shown below, followed by the organization of the status register.
