23.1 Functional Description
This chapter describes the functionality of the MLI interface.
• A general introduction to the interface (see Page 23-2)
• The MLI frame structure for data exchange (see Page 23-10)
23.1.1 General Introduction
The introduction comprises:
• An overview about the MLI (see Page 23-2)
• Naming conventions (see Page 23-3)
• A description of the MLI communication principles (see Page 23-6)
23.1.1.1 MLI Overview
The Micro Link Interface (MLI) is a fast synchronous serial interface to exchange data
between microcontrollers or other devices, such as stand-alone peripheral components.
Figure 23-1 shows how two microcontrollers are typically connected together via their
MLI interfaces.

Features
• Synchronous serial communication between an MLI transmitter and an MLI receiver
• Different system clock speeds supported in MLI transmitter and MLI receiver due to
full handshake protocol (4 lines between a transmitter and a receiver)
• Fully transparent read/write access supported (= remote programming)
