PRS – Peripheral Reflex System

Quick Facts

What?

The PRS is available in Energy Mode 0 and Energy Mode 1 and allows configurable, fast, and autonomous connections between the peripherals.

Why?

Events and signals from one peripheral can be used as input signals or triggers by other peripherals and ensure timing-critical operation and reduced software overhead.

How?

Without CPU intervention the peripherals interconnect via the PRS and signal events/states or even transfer data autonomously in single- or chained steps. This results in improved system performance and reduced energy consumption. The Peripheral Reflex System (PRS) system is a configurable network which lets the different peripheral modules communicate directly with each other without involving the CPU. Peripherals sending out Reflex signals are called producers. The PRS routes these reflex signals to consumer peripherals, which act on the received data.
