16.3.4 DMA addressing control registers 0 to 3 (DADC0 to DADC3)
to 3). These registers cannot be accessed during a DMA operation.
650
The DADC0 to DADC3 registers are 16-bit registers that control the DMA transfer mode for DMA channel n (n = 0
These registers can be read or written in 16-bit units.
Reset sets these registers to 0000H.
Cautions 1. The DSn0 bit sets how many bits of data is to be transferred.
2. Set the DADCn register when the target channel is in one of the following periods (the
If the transfer data size is set to 16 bits, transfer is always started from an address with the
lowest bit of the address aligned to “0”. In this case, transfer cannot be started from an odd
address.
operation is not guaranteed if the register is set at any other time).

• Period from completion of DMA transfer (after terminal count) to the generation of the next
• Period from forced termination of DMA transfer (after the DCHCn.INITn bit was set to 1) to
