5.17 PDMA Controller (PDMA)
5.17.1 Overview
5.17.2 Features
NuMicro™ NUC100 Medium Density contains a peripheral direct memory access (PDMA)
controller that transfers data to and from memory or transfer data to and from APB devices. The
PDMA has nine channels of DMA (Peripheral-to-Memory or Memory-to-Peripheral or Memory-to-
Memory). For each PDMA channel (PDMA CH0~CH8), there is one word buffer as transfer buffer
between the Peripherals APB devices and Memory.
Software can stop the PDMA operation by disable PDMA [PDMACEN]. The CPU can recognize
the completion of a PDMA operation by software polling or when it receives an internal PDMA
interrupt. The PDMA controller can increase source or destination address or fixed them as well.
Notice: NuMicro™ NUC100 Low Density only has 1 PDMA channel (channel 0).
Up to nine DMA channels. Each channel can support a unidirectional transfer (Low
Density only has 1 PDMA channel)
AMBA AHB master/slave interface compatible, for data transfer and register read/write
Support source and destination address increased mode or fixed mode
Hardware channel priority. DMA channel has the highest priority and channel has the
lowest priority
