These registers are used to set the peripheral I/O register address for DMA channel n.
These registers are can be read/written in 16-bit units.
These registers are used to set the internal RAM address for DMA channel n. An address is incremented after
each transfer is completed, when the DADn bit of the DCHDn register is 0. The incrementation value is “1” during
8-bit transfers and “2” during 16-bit transfers (n = 0 to 2).
These registers are can be read/written in 16-bit units.
Caution The following peripheral I/O registers must not be set in DIOAn.
703015AY, 703015B, 703015BY, 70F3015B, and 70F3015BY.
