Micro Link Serial Bus Interface (MLI0)
The Micro Link Interface is a fast synchronous serial interface that allows data exchange
between microcontrollers of the 32-bit AUDO microcontroller family without intervention
of a CPU or other bus masters. Figure 3-8 shows how two microcontrollers are typically
connected together via their MLI interfaces. The MLI operates in both microcontrollers
as a bus master on the system bus.

Features
• Synchronous serial communication between MLI transmitters and MLI receivers
located on the same or on different microcontroller devices
• Automatic data transfer/request transactions between local/remote controller
• Fully transparent read/write access supported (= remote programming)
• Complete address range of remote controller available
• Specific frame protocol to transfer commands, addresses and data
• Error control by parity bit
• 32-bit, 16-bit, and 8-bit data transfers
• Programmable baud rates
– MLI transmitter baud rate: max. f_MLI/2 (= 40 Mbit/s @ 80 MHz module clock)
– MLI receiver baud rate: max. f_MLI
• Multiple remote (slave) controllers are supported
MLI transmitter and MLI receiver communicate with other off-chip MLI receivers and MLI
transmitters via a 4-line serial I/O bus each. Several I/O lines of these I/O buses are
available outside the MLI module kernel as four-line output or input buses.
