Section 7 DMA Controller (Not Supported in the H8S/2321)
Bit 6—Destination Address Increment/Decrement (DAID)
Bit 5—Destination Address Increment/Decrement Enable (DAIDE): These bits specify
whether destination address register MARB is to be incremented, decremented, or left unchanged,
when data transfer is performed.

Bit 4—Reserved: Can be read or written to. Only 0 should be written to this bit.
Bits 3 to 0—Data Transfer Factor (DTF3 to DTF0): These bits select the data transfer factor
(activation source). The factors that can be specified differ between normal mode and block
transfer mode.

•
When DTSZ = 0, MARB is incremented by 1 after a transfer
When DTSZ = 1, MARB is incremented by 2 after a transfer
When DTSZ = 0, MARB is decremented by 1 after a transfer
When DTSZ = 1, MARB is decremented by 2 after a transfer
