5.18 PDMA Controller (PDMA)
5.18.1 Overview
5.18.2 Features
NuMicro™ NUC130/NUC140 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: The partial of NuMicro™ NUC130/NUC140 only has 1 PDMA channel (channel 0).
NuMicro™ NUC130/NUC140 Technical Reference Manual
Support nine DMA channels. Each channel can support a unidirectional transfer
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 0 has the highest priority and channel 8 has the
lowest priority
