Software Data Protection
Software Data Protection (SDP) is employed to protect
the entire array against inadvertent writes. To write to
the X68257, a three-byte command sequence must
precede the byte(s) being written.
All write operations, both the command sequence and
any data write operations must conform to the page write
timing requirements.
