11. ID Check
This command checks the ID code. Figure 1.190 shows the ID check command timing. To execute the boot ID check
command:
(1) Transfer the "F5
(2) Transfer addresses A
respectively.
(3) Transfer the number of data sets of the ID code with the 5th byte.
(4) The ID code is sent with the 6th byte on, starting with the 1st byte of the code.
See the ID code section for more information.
12. Download Command
This command downloads a program to the RAM for execution. Figure 1.191 shows the download command timing. To
execute the download command:
(1) Transfer the "FA
(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 from the 5th byte on.
(4) The program to execute is sent starting with the 5th byte.
When all data has been transmitted, if the check sum matches, the downloaded program is executed. The size of the
program will vary according to the internal RAM.
