20.3 Registers
760
(1) DMA source address registers 0 to 3 (DSA0 to DSA3)
Cautions 1. Be sure to clear bits 14 to 10 of the DSAnH register to 0.
The DSA0 to DSA3 registers set the DMA source addresses (26 bits each) for DMA channel n (n = 0 to 3).
These registers are divided into two 16-bit registers, DSAnH and DSAnL.
These registers can be read or written in 16-bit units.
2. Set the DSAnH and DSAnL registers during one of the following periods in which DMA
3. When the value of the DSAn register is read, two 16-bit registers, DSAnH and DSAnL, are
4. DMA transfer of misaligned 16-bit data with is not supported.
5. Following a reset, set the DSAnH, DSAnL, DDAnH, DDAnL, and DBCn registers before

Cautions).
If an odd address is specified as the transfer source, the least significant bit of the
address is forcibly handled as being 0.
starting DMA transfer. If these registers are not set, DMA transfers are not guaranteed.

• 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

During DMA transfer, the next DMA transfer source address is held.
When DMA transfer is completed, the DMA address set first is held.

During DMA transfer, the next DMA transfer source address is held.
When DMA transfer is completed, the DMA address set first is held.
