4. Execute an erase interlock write to any CMF array location.
5. Write EHV = 1 in the CMFCTL register.
6. Read the CMFCTL register until HVS = 0.
7. Write EHV = 0 in the CMFCTL register.
8. To verify the erase operation, read all locations that are being erased, including
9. To reduce the time used for erase margin reads, upon the first read of a zero,
