ABSTRACT:
Disclosed is a communication control microcomputer which includes components that implement serial communication control in compliance with a communication protocol, a FIFO memory for temporarily holding transaction data, a direct memory access control (DMAC) for implementing DMA transfer between the FIFO memory and the main memory, and a CPU for implementing general control over these components. A signal indicating end of frame (transaction data) is passed between components that control the serial communication and the DMAC through the FIFO memory.
