UFM-ERASE
The UFM-ERASE (CE) instruction erases both UFM sector 0 and sector 1 for SPI
Extended Mode. While for SPI Base mode, the CE instruction has the same
functionality as the SECTOR-ERASE (SE) instruction, which erases UFM sector 0 only.
WEN bit and the UFM sectors must not be protected for CE 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 CE
cycle. For both SPI Extended mode and Base mode, the CE operation is performed in
the following sequence as shown in
1. nCS is pulled low.
2. Opcode 01100000 is transmitted into the interface.
3. nCS is pulled back to high.
