Write Enable (WREN)
The Write Enable (WREN) instruction (
Figure 7.
)
sets the Write Enable Latch (WEL) bit.
The Write Enable Latch (WEL) bit must be set pri-
or to every Page Write (PW), Page Program (PP),
Page Erase (PE), and Sector Erase (SE) instruc-
tion.
The Write Enable (WREN) instruction is entered
by driving Chip Select (S) Low, sending the in-
struction code, and then driving Chip Select (S)
High.
Figure 7. Write Enable (WREN) Instruction Sequence
Write Disable (WRDI)
The Write Disable (WRDI) instruction (
Figure 8.
)
resets the Write Enable Latch (WEL) bit.
The Write Disable (WRDI) instruction is entered by
driving Chip Select (S) Low, sending the instruc-
tion code, and then driving Chip Select (S) High.
The Write Enable Latch (WEL) bit is reset under
the following conditions:
–
