requests issued by on-chip peripheral I/O (serial interfaces, timer/counters, and A/D converter), interrupts from
external input pins, or software triggers (memory refers to internal RAM or external memory).
20.1 Features
The V850ES/JG3-L includes a direct memory access (DMA) controller (DMAC) that executes and controls DMA
The DMAC controls data transfer between memory and I/Os, between memories, or between I/Os based on DMA
• 4 independent DMA channels
• Transfer unit: 8/16 bits
• Maximum transfer count: 65,536 (2
• Program execution using internal ROM during DMA transfer
• Transfer type: Two-cycle transfer
• Transfer mode: Single transfer mode
• Transfer requests
• Transfer sources and destinations
• Data transfer between buses that have different bus widths
• Request by interrupts from on-chip peripheral I/Os (serial interfaces, timer/counters, A/D converter) or
• Requests triggered by software
• Internal RAM ↔ On-chip peripheral I/O
• On-chip peripheral I/O ↔ On-chip peripheral I/O
• Internal RAM ↔ External memory
• External memory ↔ On-chip peripheral I/O
• External memory ↔ External memory
