(7) Switching function
(8) Registers related to DMAC
(a) Switching between one-shot transfer and repeated transfer
• A fixed address from an arbitrary 1M byte space, one-shot transfer ..................................... P2-148
• An arbitrary 1M byte space from a fixed address, repeated transfer ..................................... P2-150
Figure 2.9.1 shows the memory map of DMAC-related registers, and Figures 2.9.2 and 2.9.3 show
DMAC-related registers.
'One-shot transfer' refers to a mode in which DMA is disabled after the transfer counter underflows.
'Repeated transfer' refers to a mode in which a reload is carried out after the transfer counter under-
flows. The reload is carried out for the transfer counter and on the address pointer subjected to
forward direction.
The following are examples of operation in which the options listed are selected.
