Introduction
2.5.5 Micro Link Serial Bus Interface
This TC1197 contains two Micro Link Serial Bus Interfaces, MLI0 and MLI1.
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 9 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)
⢠Complete address range of target device available
⢠Specific frame protocol to transfer commands, addresses and data
⢠Error detection by parity bit
⢠32-bit, 16-bit, or 8-bit data transfers supported
⢠Programmable baud rate: fMLI/2 (max. fMLI = fSYS)
⢠Address range protection scheme to block unauthorized accesses
⢠Multiple receiving devices supported
