Section 14 Direct Memory Access Controller (DMAC)
14.3.1
SAR is 32-bit readable/writable registers that specify the source address of a DMA transfer.
During a DMA transfer, these registers indicate the next source address.
To transfer data in word or in longword units, specify the address with word or longword address
boundary. When transferring data in 16-byte or in 32-byte units, a 16-byte or 32-byte boundary
must be set for the source address value. The initial value is undefined.
