Interrupt processing:
External interrupt
2 points (Response 4 points (Response time of 0.3 ms max.)
time of 0.3 ms max.)
Memory protection
Memory backup
Maintains the contents of the HR, AR, Counter and Data Memory Areas.
Flash memory: User program, data memory (Read only) (Non-battery powered stor-
age)
Super capacitor: Data memory (Read/Write), holding bits, auxiliary memory bits, count-
er (20-day storage at an ambient temperature of 25"C)
Self-diagnostic function
Program check
CPU error (watchdog timer), memory errors, I/O bus errors
No END instruction programming errors (constantly checked during operation)
