OPERATION MODE SETTING METHOD FOR PERIPHERAL CIRCUIT OF MICROCOMPUTER SYSTEM, MEMORY DIAGNOSIS METHOD AND MICROCOMPUTER SYSTEM

摘要

PPROBLEM TO BE SOLVED: To enable to perform an operation mode setting for a peripheral circuit of a microcomputer system and a memory diagnosis in a short time. PSOLUTION: A CPU 20 executes the control to store a plurality of set data corresponding to a plurality of addresses set on a peripheral circuit 22 into an NVM 23, activates a DMA control means, and executes the setting including access by the address of a transfer source and a transfer destination for the DMA activation. A DMA controller 21 executes a DMA transfer of a plurality of set data stored in the NVM 23 by the activation of the CPU 20 to the peripheral circuit 22 in response to the address of the peripheral circuit 22.
