The controller has three system interfaces attached to the PMC IOP switch.
AXI Master DMA Interface
The AXI master DMA interface enables the controller to burst data from the flash device to system memory in DMA access mode. For more information, see DMA Programming Model.
AXI Access Interface
An AXI interface enables software to read and write flash memory data. The interface is used in several controller operating modes.
- Direct access mode
- Indirect mode non-DMA
APB Programming Interface
The APB programming interface enables software to access the memory mapped control and status registers.
The control and status registers are listed in the Register Reference section.
