Write Enable ( WREN ) and Write
Disable ( WRDI )
The following is a list of conditions under which the
write enable latch will be reset:
The 25XX320 contains a write enable latch. See
Table 3-3 for the Write-Protect Functionality Matrix.
This latch must be set before any write operation will be
completed internally. The WREN instruction will set the
latch, and the WRDI will reset the latch.
