Write Enable (WREN) and Write
Disable (WRDI)
The 25xx040 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.
The following is a list of conditions under which the
write enable latch will be reset:
Power-up
WRDI instruction successfully executed
WRSR instruction successfully executed
WRITE instruction successfully executed
WP line is low
