Instructions
Each instruction starts with a single-byte code, as summarized in
If an invalid instruction is sent (one not contained in
deselects itself.
Table 3.
1. Address bit A10 must be 0, all other address bits are Don't Care.
2. Address bit A10 must be 1, all other address bits are Don't Care.
Write Enable (WREN)
The Write Enable Latch (WEL) bit must be set prior 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
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 a the device to be deselected, by Chip Select (S) being driven
high.
