Hi,
You can use UART Communcation (Rx & Tx Lines or pins) to communicate between 8051 & MSP, make sure that bidirectional voltage translator is used between the serial connection because 8051 operates on 5V & most MSP operates on 3.3V. Also make sure that both the controllers operates on same voltage source if not you need isolator between them for differnt voltage source
