Download Command
This command downloads a program to the RAM for execution.
Execute the download command as explained here following.
(1) Transfer the “FA
” command code with the 1st byte.
16
(2) Transfer the program size with the 2nd and 3rd bytes.
(3) Transfer the check sum with the 4th byte. The check sum is
added to all data sent with the 5th byte onward.
(4) The program to execute is sent with the 5th byte onward.
When all data has been transmitted, if the check sum matches,
