DMA Destination Address Register (DDAR)

DDAR is a 32-bit readable/writable register that specifies the transfer destination address. DDAR
updates the transfer destination address every time data is transferred. When DSAR is specified as
the source address (the DIRS bit in DACR is 0) in single address mode, DDAR is ignored.
Although DDAR can always be read from by the CPU, it must be read from in longwords and
must not be written to while data for the channel is being transferred.
