8.1
The H8/3048B Group has an on-chip DMA controller (DMAC) that can transfer data on up to four
channels.
When the DMA controller is not used, it can be independently halted to conserve power. For
details see section 20.6, Module Standby Function.
8.1.1
DMAC features are listed below.
Selection of short address mode or full address mode
Short address mode:
Full address mode:
Directly addressable 16-Mbyte address space
Selection of byte or word transfer
