(4) DMA addressing control registers 0 to 3 (DADC0 to DADC3)
Cautions 1. Be sure to clear bits 15, 13 to 8, and 3 to 0 of the DADCn register to 0.
The DADC0 to DADC3 registers are 16-bit registers that control the DMA transfer mode for DMA channel n (n
= 0 to 3).
These registers can be read or written in 16-bit units.
Reset sets these registers to 0000H.
2. Set the DADCn register during one of the following periods in which DMA transfer is
3. The DSn0 bit specifies the size of the transfer data, and does not control bus sizing. For
4. If the transfer data size is set to 16 bits (DS0 bit = 1), transfer cannot be started from an

odd address. Transfer is always started from an address with the first bit of the lower
address aligned to 0.
destination), be sure to specify the same transfer size as the register size. For example, to
execute DMA transfer on an 8-bit register, be sure to specify 8-bit transfer.
