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.
