nor lost bits whilst in storage. The CHECKSUM
of a device which has
programmed wrongly, gives useful information: if
it is too low than
the device has extra bits programmed and was

If the CHECKSUM is too high then the device has
bits which will not
program - it may be damaged or the wrong
algorithm is being used.
A PROM used as a MASTER to prepare copies for
sale as firmware should
be marked with its checksum. The checksum of
the slaves should be
taken and matched against the master.

Wild characters
