(2) DMA destination address registers 0 to 3 (DDA0 to DDA3)
Cautions 1. Be sure to clear bits 14 to 10 of the DDAnH register to 0.
The DDA0 to DDA3 registers set the DMA destination address (26 bits each) for DMA channel n (n = 0 to 3).
These registers are divided into two 16-bit registers, DDAnH and DDAnL.
These registers can be read or written in 16-bit units.
2. Set the DDAnH and DDAnL registers at the following timing when DMA transfer is disabled
3. When the value of the DDAn register is read, two 16-bit registers, DDAnH and DDAnL, are
4. Following reset, set the DSAnH, DSAnL, DDAnH, DDAnL, and DBCn registers before

Cautions).
starting DMA transfer. If these registers are not set, the operation when DMA transfer is
started is not guaranteed.
• Period from after reset to start of first DMA transfer
• Period from after channel initialization by DCHCn.INITn bit to start of DMA transfer
• Period from after completion of DMA transfer (DCHCn.TCn bit = 1) to start of the next

Set an address (A25 to A16) of DMA transfer destination
(default value is undefined).
During DMA transfer, the next DMA transfer destination address is held.
When DMA transfer is completed, the DMA transfer source address set
first is held.
Set an address (A15 to A0) of DMA transfer destination
(default value is undefined).
During DMA transfer, the next DMA transfer destination address is held.
When DMA transfer is completed, the DMA transfer source address set
first is held.
