WRITE OPERATIONS
The CAT15008/16 device powers up into a write
disable 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.
Write Enable and Write Disable
The
internal
Write
Enable
Latch
and
the
corresponding Status Register WEL bit are set by
sending the WREN instruction to the CAT15008/16.
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 4. The WREN
instruction must be sent prior any WRITE or WRSR
instruction.
The internal write enable latch is reset by sending the
WRDI instruction as shown in Figure 5. Disabling write
operations by resetting the WEL bit, will protect the
device against inadvertent writes.
