This LSI has a built-in DMA controller (DMAC) which can carry out data transfer on up to 4
channels.
7.1
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, USB request, auto-request (depending on transfer mode)
• Module stop mode can be set
(1) Short address mode
(2) Full address mode
⎯ 16-bit timer-pulse unit (TPU) compare match/input capture interrupts
⎯ Serial communication interface (SCI_0) transmission complete interrupt, reception
⎯ A/D conversion end Interrupt
⎯ USB request
⎯ Auto-request
— Maximum of 4 channels can be used
— Choice of dual address mode
— In dual address mode, one of the two addresses, transfer source and transfer destination,
— Choice of sequential mode, idle mode, or repeat mode for dual address mode
— Maximum of 2 channels can be used
— Transfer source and transfer destination address specified as 24 bits
