• EraseThe UFM block supports byte write, but does not support byte erase, requiring a sector-based erase sequenceprior to any programming or writing.

Asserting READ, WRITE, and ERASE at the same time is not allowed. Multiple requests are ignored andnothing is read from, written to, or erased in the
