SECTOR-ERASE
SECTOR-ERASE (SE) is the instruction of erasing one sector of the UFM block. Each
sector contains 256 words. WEN bit and the sector must not be protected for SE
operation to be successful. nCS must be driven high before the instruction is executed
internally. You may poll the nRDY bit in the software status register for the completion
of the internal self-timed SECTOR-ERASE cycle. For SPI Extended mode, the SE
operation is performed in the following sequence, as shown in
1. nCS is pulled low.
2. Opcode 00100000 is transmitted into the interface.
3. The 16-bit address is sent. The eighth bit (the first seven bits will be discarded) of

the address indicates which sector is erased; a 0 means sector 0 (UFM0) is erased,
and a 1 means sector 1 (UFM1) is erased.
