Embodiment Construction

[0035] Hereinafter, the configuration and operation of a receiver according to one embodiment will be described with reference to the drawings. For clarity of description, the following description and drawings are partially omitted and simplified. In the drawings, the same components are denoted by the same reference symbols, and repeated descriptions will be omitted as appropriate.

[0036] figure 1is a block diagram showing the configuration of the microcomputer according to this embodiment. The microcomputer 1 includes a central processing unit (CPU) 10, an interrupt controller (INT) 11, a data transfer controller (DTC) 12, a ROM (read only memory) 13, a RAM (random access memory) 14, a bus controller (BSC) ) 15, timer 16, communication module 17, analog module 18 and input / output port (I / O) 19.

[0037] A central processing unit (CPU) 10 is a processing unit that performs overall control of the microcomputer 1, and reads out instructions from the ROM 13 to execute the ...

Abstract

A microcomputer includes a central processing unit (CPU) and a data transfer controller (DTC). The data transfer controller (DTC) reads out data transfer information including transfer mode information from a storage device (RAM) or the like. The data transfer controller (DTC) analyzes the transfer mode information to change at least one of a transfer source address, a transfer destination address, the number of transfer operations, and data transfer information that is used next.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2013-230883 filed on November 7, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a semiconductor device, and more specifically, for example, to a semiconductor device including a data transmission function. Background technique [0004] The one-chip microcomputer described on pages 540-541 of "LSI Handbook", published by Ohmsha Co., Ltd. on November 30, 1984, is composed of a central processing unit (CPU) and other functional blocks including Read Only Memory (ROM) for program storage, Random Access Memory (RAM) for data storage, and input / output circuits for input and output of data or signals, all of these blocks are formed on a single semiconductor substrate. The one-chip microcomputer is used to control the device. [0005] In the contro...
