7.1
The H8S/2655 Group has a built-in DMA controller (DMAC) which can carry out data transfer on
up to 4 channels.
7.1.1
The features of the DMAC are listed below.
Choice of short address mode or full address mode
Short address mode:
Full address mode:
16-Mbyte address space can be specified directly
Byte or word can be set as the transfer unit
Activation sources: internal interrupt, external request, auto-request (depending on transfer
mode)
Maximum of 4 channels can be used
Choice of dual address mode or single address mode
In dual address mode, one of the two addresses, transfer source and transfer destination, is
specified as 24 bits and the other as16 bits
In single address mode, transfer source or transfer destination address only is specified as
24 bits
In single address mode, transfer can be performed in one bus cycle
Choice of sequential mode, idle mode, or repeat mode for dual address mode and single
address mode
Maximum of 2 channels can be used
Transfer source and transfer destination address specified as 24 bits
Choice of normal mode or block transfer mode
Six 16-bit timer-pulse unit (TPU) compare match/input capture interrupts
Serial communication interface (SCI0, SCI1) transmission complete interrupt, reception
complete interrupt
A/D converter conversion end interrupt
External request
