Section 14 Direct Memory Access Controller (DMAC)
Dual Address Mode: Dual address mode is used to access both the transfer source and the
transfer destination by address. The transfer source and destination can be accessed by either on-
chip peripheral module or external address.
Even if the operand cache is used in RAM mode, the RAM cannot be set as the transfer source or
transfer destination.
