System Peripherals and Debug Access Port
Each Ethernet MAC, USB OTG, NAND flash controller, and SD/MMC controller module has an integrated
DMA controller. For modules without an integrated DMA controller, an additional DMA controller module
provides up to eight channels of high-bandwidth data transfers. Peripherals that communicate off-chip are
multiplexed with other peripherals at the HPS pin level. This allows you to choose which peripherals to
interface with other devices on your PCB.
The debug access port provides interfaces to industry standard JTAG debug probes and supports ARM
CoreSight debug and core traces to facilitate software development.
