18.3 Registers
632
(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 at the following timing when DMA transfer is disabled
3. When the value of the DSAn register is read, two 16-bit registers, DSAnH and DSAnL, 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 the address (A25 to A16) of the DMA transfer source
(default value is undefined).
During DMA transfer, the next DMA transfer source address is held.
When DMA transfer is completed, the DMA address set first is held.
Set the address (A15 to A0) of the DMA transfer source
(default value is undefined).
During DMA transfer, the next DMA transfer source address is held.
When DMA transfer is completed, the DMA address set first is held.
