The TA command (Beginning with Version 5.24 of the 9000 and
Version 9.33 of PGMX) allows you to calculate an 8 bit checksum
of “00” to be programmed at a specified location in your eprom.
If no location is specified (TAnnnn< cr> ) then the byte is
programmed at the last location in the eprom. What happens is
TA will calculate an 8 bit number to add to the eprom to make the
16 bit checksum “nn00h”. The LSB of the checksum is 00. If the
checksum is already 00 then no programming is done, otherwise
the TA command will attempt to program the specified location
in your eprom. All normal programming rules apply.
TC Toggle Compare Mode
The TC toggle command is used to turn the compare mode on
and off. When in the compare mode, the command prompter is
prefixed by a lower case c. The compare mode is used to
compare the contents of a device against that of a source file.
Interactively, a TC will cause the compare mode to be set, and
the next TC command will reset the compare mode. In the
automation mode, a TC on the command line will always cause
the compare mode to be set only. To reset compare mode use
the TR command.
To use the compare mode, issue a programming command as if
you were going to program the device. Instead of programming
the device, the 9000 will make a comparison of the source byte
to the contents of the device. If they are not the same, the
comparison error will cause a *CP err @nnnn error message to
be issued. See Diagnostics Section for details. AUTOMATED.
TE Toggle Echo (On/Off)
The TE command allows a person to write their interface software
more efficiently so that it does not have to handle receiving any
characters during the program process. As soon as the com-
mand is issued (ΤΕ) nothing is echoed or sent back to the
console. As long as valid commands or data are being sent to
the 9000, nothing is echoed or sent back. As soon as an error
occurs, or any time the “X” command is issued, the 9000 reverts
back to sending all characters. AUTOMATED.
