14. Direct Memory Access Controller (DMAC)
14.3.4
DARB are 32-bit readable/writable registers that specify the destination address of a DMA
transfer that is set in DAR again in repeat/reload mode. The data written to DAR by the CPU is
also written to DARB. To set the address that is different from DAR address, write data to DAR,
then, to DARB.
A word or longword boundary address should be specified when a word or longword transfer is
performed respectively. A 16-byte or 32-byte boundary value should be specified when a 16-byte
or 32-byte transfer is performed respectively.
The initial value of DARB is undefined.
