Non-Fatal Errors
These errors are considered non fatal in that the process continues,
that is, it makes you aware that there may be a problem, but you
don’t want to stop right now because it may not be an error. One ex-
ample is when you are using the V command, and you find some
non blank locations. You may have intended that those locations
have data, so the 9000 continues, but makes you aware of those
locations by issuing a message showing data and address.
Overload Conditions
If a programming voltage overload condition occurs, the 9000 will
not say “OVERLOAD”! The 9000 will not be damaged unless the part
is shorted to the data bus or address lines and you keep trying the
process several times in a row before realizing the part will not pro-
gram.
The key indication is a *NE error or a *WP error. Do something other
than trying to immediately program the part again without checking
the menu selection you have made or erasing the part.
