Datasheet

– Two recoverable fault sources
– Two non-recoverable fault sources
– Debugger can be source of non-recoverable fault
• Input events:
– Two input events (EVx) for counter
– One input event (MCx) for each channel
• Output events:
– Three output events (Count, Re-Trigger and Overflow) available for counter
– One Compare Match/Input Capture event output for each channel
• Interrupts:
– Overflow and Re-Trigger interrupt
– Compare Match/Input Capture interrupt
– Interrupt on fault detection
• Can be used with DMA and can trigger DMA transactions
