DMA Function

DMA, which transfers data

without CPU intervention,

supports up to four channels.

The DMA-II/DTC function

provides many other memory

transfer capabilities, such as

transfer of multiple bytes by

a single event and transfer of

data to multiple addresses by a

single event (M32C/80 core,

R32C/100 core).
