Programming a Device From PC Memory

Operating in the Display Window
This message is updated when the programmer starts programming the next
packet.
If, for some reason, you want to terminate the programming process before it
is completed, press the
key to abort the process and return to the display
command menu.
When the programming process is either completed or aborted, a message
informs you whether or not the programming was successful. The message
for successful programming is:
Programming Complete, Program another device?(y/n)
If you want to program another device using the same parameter values, re-
place the device in the programmer with the new one and press
.
The message for an unsuccessful programming operation is:
Error occurred during programming. (hit any key)
Press any key to erase the error message and return to the display command
menu. Use the
show command to look at the error file and find the error loca-
tion(s).
Automatic verification takes place during the programming. The programmer
reads, from the device, data bytes just programmed and compares them with
the source data bytes. If the data bytes are not programmed correctly, an error
file is generated. Both the source and the read-back values of the data bytes
are included in this file. An error file is not generated if no errors have occurred
during programming. The format of the error file is illustrated below.

Verification output by byte:
Address
Byte Value
(downloaded) Byte Value
(read back)
7070 b4 ff
In the example above, the device location 7070h should have been
programmed with value
B4h, but the value read back from the device is FFh.
