Section 10 Direct Memory Access Controller (DMAC)
• External request detection: There are following four types of DREQ input detection.
⎯ Low level detection
⎯ High level detection
⎯ Rising edge detection
⎯ Falling edge detection
• Transfer request acknowledge and transfer end signals: Active levels for DACK and TEND
can be set independently.
• Support of reload functions in DMA transfer information registers: DMA transfer using the
same information as the current transfer can be repeated automatically without specifying the
information again. Modifying the reload registers during DMA transfer enables next DMA
transfer to be done using different transfer information. The reload function can be enabled or
disabled independently in each channel or reload register.
