17.1 Overview

The real-time interrupt (RTI) module provides timer functionality for operating systems and for

benchmarking code. The RTI module can incorporate several counters that define the timebases needed

for scheduling in the operating system.

The timers also allow you to benchmark certain areas of code by reading the values of the counters at the

beginning and the end of the desired code range and calculating the difference between the values.

17.1.1 Features

The RTI module has the following features:

• Two independent 64 bit counter blocks

• Four configurable compares for generating operating system ticks or DMA requests. Each event can

be driven by either counter block 0 or counter block 1.

• Fast enabling/disabling of events

• Two time stamp (capture) functions for system or peripheral interrupts, one for each counter block

• Digital windowed watchdog

17.1.2 Industry Standard Compliance Statement

This module is specifically designed to fulfill the requirements for OSEK (Offene Systeme und deren

Schnittstellen für die Elektronik im Kraftfahrzeug, or Open Systems and the Corresponding Interfaces for

Automotive Electronics) as well as OSEK/time-compliant operating systems, but is not limited to it.
