state. The device contains a Write Enable Latch (WEL)
which must be set before attempting to write to the memory
array or to the status register. In addition, the address of the
memory location(s) to be written must be outside the
protected area, as defined by BP0 and BP1 bits from the
status register.

instruction to the CAT25080/160. Care must be taken to take
the CS input high after the WREN instruction, as otherwise
the Write Enable Latch will not be properly set. WREN
timing is illustrated in Figure 3. The WREN instruction must
be sent prior to any WRITE or WRSR instruction.
WRDI instruction as shown in Figure 4. Disabling write
operations by resetting the WEL bit, will protect the device
against inadvertent writes.
