The following are key features of the EVSYS module:

• Up to 32 configurable event channels:
  • All channels can be connected to any event generator
  • All channels provide a pure asynchronous path
  • Configurable number of channels which can provide a resynchronized or synchronous path using their dedicated generic clock (GCLK_EVSYS_CHANNEL_n)
• Device-specific event generators
• Device-specific event users
• Configurable edge detector
• Peripherals can be event generators, event users, or both
• SleepWalking and interrupt for operation in sleep modes
• Software event generation
• Each event user can choose which channel to respond to
• Optional Static or Round-Robin interrupt priority arbitration
