PROM Programming Examples
If an error occurs during programming or if the PROM is defective and one or
more of the bits cannot be programmed to match the RAM data, the following
message is displayed:
Key-in Sequence
....-= ?
j; PROG
'LsssssA
The address at which the error was detected is displayed in the address field. A pro
gram error is most often caused by a faulty PROM. Pressing the CLEAR key lets
you program another blank PROM with the same information.
Copying a Development System File to a PROM
The iUP-201A universal programmer can copy a file from a development system
into its RAM buffer either on-line with the iPPS software or off-line. Once the file
is in the RAM, you can copy it into a PROM off-line.
In on-line mode, use the COPY FILE TO URAM command. (Note that in on-line
mode, the term URAM refers to the RAM buffer in the iUP-201A universal
programmer.) In the following example, the data from file CODE4.IUP on drive 1
is copied (starting at address 380H in the file) to the RAM (starting at URAM ad
dress 00H).
PPS>COPY :F1 :CODE4.IUP(380,7FF) TO URAM
CHECKSUM = 6472
PPS>
You can then program a PROM from the RAM off-line, as in the following
example.
