Section 9 Direct Memory Access Controller (DMAC)
9.2
9.2.1
DMA source address registers 0–3 (SAR0–SAR3) are 32-bit read/write registers that specify the
source address of a DMA transfer. During a DMA transfer, these registers indicate the next source
address (in single-address mode, SAR is ignored in transfers from external devices with DACK to
memory-mapped external devices or external memory).
The initial value after a reset or in standby mode is undefined.
9.2.2
DMA destination address registers 0–3 (DAR0–DAR3) are 32-bit read/write registers that specify
the destination address of a DMA transfer. During a DMA transfer, these registers indicate the
next destination address (in single-address mode, DAR is ignored in transfers from memory-
mapped external devices or external memory to external devices with DACK). The initial value
after a reset or in standby mode is undefined.
