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
CS
bits are written. The timing sequence to write to the status
register is shown below, followed by the organization of the
status register.

Power ? Up State
The serial SRAM enters a know state at power ? up time. The device is in low ? power standby state with CS = 1. A low level
on CS is required to enter an active state.
