(2) HDMADn (DMA Transfer Destination Address Setting Register)
The HDMADn register is used to set the DMA transfer destination address. When the
destination address is updated by DMA execution, HDMADn is also updated.
HDMAD0 to HDMAD5 have the same configuration.
Although the bus sizing function is supported, the address alignment function is not
supported. Therefore, specify an even-numbered address for transferring 2 bytes and an
address that is an integral multiple of 4 for transferring 4 bytes.
