Section 9 Direct Memory Access Controller (DMAC)
• Two types of DMAC channel priority ranking:
 Fixed priority mode: Channel priorities are permanently fixed.
 Round robin mode: Sets the lowest priority for the channel that last received an execution
request.
• An interrupt request can be sent to the CPU on completion of the specified number of
transfers.
• Chain transfer allows a specified block of data to be transferred consecutively without CPU
processing after the end of the current data transfer.
• A transfer end signal (TEND) can be output for each channel at the end of DMA transfer.
