• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family/H8S/2300 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

Section 7 DMA Controller (DMAC)
• DMA control register_1A (DMACR_1A)
• DMA control register_1B (DMACR_1B)
• DMA band control register H (DMABCRH)
• DMA band control register L (DMABCRL)
• DMA write enable register (DMAWER)
• DMA terminal control register (DMATCR)
The functions of MAR, IOAR, ETCR, DMACR, and DMABCR differ according to the transfer
mode (short address mode or full address mode). The transfer mode can be selected by means of
the FAE1 and FAE0 bits in DMABCRH. The register configurations for short address mode and
full address mode of channel 0 are shown in table 7.2.
