Write Enable (
WREN
) and Write
Disable (
WRDI
)
The 25XX512 contains a write enable latch. See
Table 2-4 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
PE
instruction successfully executed
SE
instruction successfully executed
CE
instruction successfully executed
