@x The @x command loads program/data section(s), byte by byte, into the RAM/EPROM. A program
algorithm detects the correct download section (in the RAM or EPROM) and runs automatically. The
transfer can be made by using a keyboard or by file transfer (pull-down menu Transfers/Send Text
File in Hyperterminal program). If download is performed manually, it can be terminated with a q
keystroke. Normally the data associated with the load command is a content of linker or
assembler-generated program/data files.
Figure 2–14 is an example of the format of such a program/data file:

Figure 2–14. Transfer Data Command
The @x command sets the memory-modification address to the address where program/data files are
stored. All code lines following the @x command represent data in byte format. These bytes will be copied
sequentially to the specified section address. The q command terminates the section input and returns the
control back to the Monitor Program.
NOTE: Programming an EPROM
While programming the EPROM, be sure that the file being used has the correct section
addresses and contains the correct program/data. Programming an EPROM location once will
prevent a second programming at this location in the STK. For more information see the
Hardware Installation section in this manual.
