MIPI LLI uses the MIPI M-PHY physical layer. The MIPI LLI stack also provides a PHY adapter, data link layer and transaction layer.
The interface also allows for sideband signals between the two chips to further improve overall system communication. Operation on MIPI M-PHY can reduce system power by leveraging the MIPI M-PHY sleep and hibernation power modes.
MIPI M-PHY can also scale data throughput. The connections employ memory-mapped transactions for communications via native protocols such as Open Core Protocol and Advanced Microcontroller Bus Architecture.
