Write Enable ( WREN ) and Write
Disable ( WRDI ) Instructions
The following is a list of conditions under which the
write enable latch will be reset:
The 11XX contains a write enable latch. See Table 6-1
for the Write-Protect Functionality Matrix. This latch
must be set before any write operation will be com-
pleted internally. The WREN instruction will set the
latch, and the WRDI instruction will reset the latch.
Note: The WREN and WRDI instructions must
be terminated with a NoMAK following
the command byte. If a NoMAK is not
received at this point, the command will
be considered invalid, and the device
will go into Idle mode without responding
with a SAK or executing the command.
