7.17.1.1 Features
7.16.2 Serial GPIO (SGPIO)
7.17.1 General Purpose DMA (GPDMA)
7.17 AHB peripherals
The Serial GPIOs offer standard GPIO functionality enhanced with features to accelerate
serial stream processing.
The DMA controller allows peripheral-to memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receives. The
source and destination areas can each be either a memory region or a peripheral for
master 1, but only memory for master 0.

Each SGPIO input/output slice can be used to perform a serial to parallel or parallel to
serial data conversion.
16 SGPIO input/output slices each with a 32-bit FIFO that can shift the input value
from a pin or an output value to a pin with every cycle of a shift clock.
Each slice is double-buffered.
Interrupt is generated on a full FIFO, shift clock, or pattern match.
Slices can be concatenated to increase buffer size.
Each slice has a 32-bit pattern match filter.
Eight DMA channels. Each channel can support an unidirectional transfer.
16 DMA request lines.
Single DMA and burst DMA request signals. Each peripheral connected to the DMA
Controller can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the DMA Controller.
Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers are supported.
Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
Hardware DMA channel priority.
AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
Two AHB bus masters for transferring data. These interfaces transfer data when a
DMA request goes active. Master 1 can access memories and peripherals, master 0
can access memories only.
32-bit AHB master bus width.
Incrementing or non-incrementing addressing for source and destination.
Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data.
