• Single transfer mode
• Repeat transfer mode
When the DMA enable bit is set to “1”, the DMAC is active.
When the DMAC is active, data transfer starts every time a DMA
transfer request signal occurs.
• When the DMA enable bit is set to “0”, the DMAC is inactive.
• After the transfer counter underflows in single transfer mode
At the time of starting data transfer immediately after turning the DMAC active, the
value of one of source pointer and destination pointer - the one specified for the
forward direction - is reloaded to the forward direction address pointer, and the value
of the transfer counter reload register is reloaded to the transfer counter.
Registers specified for forward direction transfer are always write enabled.
Registers specified for fixed address transfer are write-enabled when
the DMA enable bit is “0”.
Can be read at any time.
However, when the DMA enable bit is “1”, reading the register set up as the
forward register is the same as reading the value of the forward address pointer.
(Note that DMA-related registers [0020
