4. nCS is pulled back to high.
For SPI Base mode, the SE instruction erases UFM sector 0. Because there are no
choices of UFM sectors to be erased, there is no address component to this instruction.
The SE operation is always done through the following sequence in SPI Base mode:
1. nCS is pulled low.
2. Opcode 00100000 is transmitted into the interface.
3. nCS is pulled back to high.
