Use this sequence to enable the high voltage to the array or shadow
information for erase operation:
10. Make sure that CMFRMTR is in its reset state.
1. Make sure that CMFRMTR is in its reset state, and write
2. In CMFRMCR, write PROTECT[7:0] to disable protection of the
3. Use the procedure in
4. Execute an erase interlock write to any array location.
5. In CMFRCTL, write EHV = 1.
6. Read CMFRCTL until HVS = 0.
7. In CMFRCTL, write EHV = 0.
8. Verify the erase by reading all locations that are being erased,
9. In CMFRCTL, write SES = 0.

including the shadow information if the block that contains it is
erased. Off-page reads are erase margin reads that update the
read page buffer. If all the locations read as erased, continue to
the next step otherwise, update PAWS and NVR (if required, see
Table
To reduce the time for verification, upon the first read of a 0, go to
step 5. After a location has been verified (all bits are erased), it is
not necessary to reverify locations after subsequent erase pulses.
