Step 3)
When "Operation mode" is ready , go to the next step.
10.
"Local CPU" reads 24-bit data (for example, 12 3456h) from "ADC".
(The system also can use an appropriate "ADC reading start request" as a trigger.)
11.
"Local CPU" writes 24-bit data of "ADC" to the "Port data memory" of "G9006".
(Write "ADDR (0) = 12 3456h" from "Local CPU" to the "Port data memory".)
12.
"Center CPU" recognizes and reads "Input change" interrupt of the "Center LSI".
("G9006" automatically responds with "Response frame" and updates the "Port data" of "Center LSI".)
13.
"Local CPU" can repeat the operation from the procedure "10" of step 3 described above.
("Local CPU" can automatically communicate with "Center LSI" by reading from "ADC" and writing to "G9006".)
