Data transmission method and apparatus for interfacing between main system and microcomputer

摘要

In a data transmission apparatus for transmitting data between a main system and a microcomputer a controller generates transmission control signals based on first control signals received from the main system, and a memory system receives the transmission control signals and second control signals from the microcomputer. The memory system transfers data between the main system and the microcomputer based on the transmission control signals and the second control signals.
