To complete the Write Status Register instruction, the /CS pin must be driven high after the eighth or
sixteenth bit of data that is clocked in. If this is not done the Write Status Register instruction will not be
executed. If /CS is driven high after the eighth clock (compatible with the 25X series) the CMP, QE and
SRP1 bits will be cleared to 0.
During non-volatile Status Register write operation (06h combined with 01h), after /CS is driven high, the
self-timed Write Status Register cycle will commence for a time duration of tW (See AC Characteristics).
While the Write Status Register cycle is in progress, the Read Status Register instruction may still be
accessed to check the status of the BUSY bit. The BUSY bit is a 1 during the Write Status Register cycle
and a 0 when the cycle is finished and ready to accept other instructions again. After the Write Status
Register cycle has finished, the Write Enable Latch (WEL) bit in the Status Register will be cleared to 0.
During volatile Status Register write operation (50h combined with 01h), after /CS is driven high, the
Status Register bits will be refreshed to the new values within the time period of tSHSL2 (See AC
Characteristics). BUSY bit will remain 0 during the Status Register bit refresh period.
Please refer to 10.1 for detailed Status Register Bit descriptions. Factory default for all status Register
bits are 0.
