Section 11 Direct Memory Access Controller (DMAC)
11.9
The number of bits (transfer data size) for a single data transfer can be selected from among the
byte (8 bits), word (16 bits), and the longword (32 bits).
Figure 11.12 is an example of DMA data-byte control for a 32-bit wide bus.
This transfer data size cannot exceed either of the data bus bit widths supported by the source and
destination for DMA transfer. The data bus widths are fixed by the hardware.
