The maximum number of generators, Event Shapers, channels, and users supported by the
Peripheral Event Controller is 64. Please refer to the Module Configuration section at the end of
this chapter for the device-specific configuration.
• Event Shapers (EVS): Instantiated for some generators, in case filtering and/or rising/falling
• Channels: One channel per user, to propagate events and follow-up the user status
• Generators generate events
• PEVC multiplexes these incoming events
• PEVC outputs Triggers to users
