7.1
The chip 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
• 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
• Module stop mode can be set
Short address 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
⎯ In single address mode, transfer source or transfer destination address only is specified as
⎯ 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
Full 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
