DMA transfer memory start address registers 0 to 7 (MAR0 to MAR7)
The MARn register specifies the subordinated 16 bits of the DMA transfer start address within the
internal RAM area for the DMA channel n (n = 0 to 7).
This register can be read or written in 16-bit units.
After reset the register content is undefined.
Figure 6-1:
DMA Transfer Memory Start Address Registers 0 to 7 (MAR0 to MAR7)
Cautions: 1. Since the internal RAM area is mapped between 3FF0000H and 3FF7FFFH the
value written to the MARn register has to be in the range from 0000H to 7FFFH.
2. The value set to the MARn register is increased by each DMA transfer of chan-
nels. It does not keep the initial value after the DMA transfer ends.
After reset:
