INSTRUCTIONS
Each instruction starts with a single-byte code, as
summarized in Table 5.
If an invalid instruction is sent (one not contained
in Table 5.), the device automatically deselects it-
self.
Table 5. Instruction Set
Write Enable (WREN)
The Write Enable Latch (WEL) bit must be set pri-
or to each WRITE and WRSR instruction. The only
way to do this is to send a Write Enable instruction
to the device.
As shown in Figure 7., to send this instruction to
the device, Chip Select (S) is driven Low, and the
bits of the instruction byte are shifted in, on Serial
Data Input (D). The device then enters a wait
state. It waits for the device to be deselected, by
Chip Select (S) being driven High.
