12.2.2 DMA Destination Address Registers 0–3 (DAR0–DAR3)
DMA destination address registers 0–3 (DAR0–DAR3) are 32-bit readable/writable registers that
specify the destination address of a DMA transfer. These registers include a count function, and
during a DMA transfer, these registers indicate the next destination address.
To transfer data in 16 bits or in 32 bits, specify a 16-bit or 32-bit address boundary address. To
transfer data in 16-bit or 32-bit units, make sure to specify a destination address with a 16-byte
boundary (16n address). Operation is not guaranteed if other addresses are specified.
The initial value is undefined in a reset. The previous value is retained in standby mode.
