A hardware pulse or level change is called Service Request (SR) in an XMC4500 system. Service Requests (SR) are the fastest way to send trigger “messages” between connected on-chip resources.

An SR can generate any of the following requests
• Interrupt
• DMA
• Peripheral action

A service request can be distributed concurrently. To support the concurrent distribution to multiple receivers, the receiving modules are capable to enable/disable incoming requests.
