Table 4. Instruction Set
Write Enable (WREN)
The Write Enable (WREN) instruction (
Figure 4
) sets the Write Enable Latch
(WEL) bit. The Write Enable Latch (WEL) bit must be set prior to every Page Pro-
gram (PP), Erase (SE or BE) and Write Status Register (WRSR) instruction. The
Write Enable (WREN) instruction is entered by driving Chip Select (CS#) Low,
sending the instruction code, and then driving Chip Select (CS#) High.
