Overview
Start the system and initialize peripheral devices.
Pre-conditions None
Post-conditions
Any of the following:
•
Calls “UC12: Select function”
•
Calls “UC61: Inspect switches”
--- Basic flow ---
1
The operator resets the C17602 CPU board.
2
The program starts, initializing the peripheral devices (CT, PORT, LCD, SVD, REMC, ADC, RFC). Certain peripheral devices
will begin operating.
