5.5.4. Combo DLL PHY System Integration
The following section describes the system components and respective features:
- SD/eMMC wrapper
- Corresponds to the SD/eMMC host controller
- Provides hardware control to perform memory operations over SD and eMMC Flash cards
- Interfaces with the combo PHY through a DFI interface
- Includes a 32-bit APB Requester interface which provides access to PHY control and status registers from the SD/eMMC host controller memory map
- NAND Flash controller wrapper
- Corresponds to the NAND Flash controller
- Provides hardware control to perform memory operations over NAND Flash devices
- Interfaces with the combo PHY through a DFI interface
- Includes a 32-bit APB Requester interface which provides access to PHY control and status registers from NAND Flash controller memory map
- Combo PHY
- Provides the DFI interface from both the SD/eMMC and NAND controller and a control input that selects the active port
- Provides an APB port for accessing control and status registers from Flash controllers (SD/eMMC and NAND controller)
- Sends all control/data signals and output enables to the pinmux using the combo PHY pin interface where the user can select the bumps that are used
- System manager
- Provides the control and status registers required for various SD/eMMC and NAND controller interfaces
- Provides a control register to select the active DFI interface to the combo PHY
- PSS NoC
- Provides APB completer ports for SD/eMMC and NAND Controller register access
- Provides AXI manager ports for the SD/eMMC and NAND controller’s built-in DMA controller
- Provides both requester and completer APB ports for SD/eMMC and NAND controller access to combo PHY registers, as well as system access to combo PHY registers
- GIC-600
- Handles interrupts from both the SD/eMMC and NAND controllers
- Reset manager
- Receives a single softphy_rst_n signal from the reset manager
For more information about other interfaces in the diagram above that are not described here, see the SD/eMMC host controller and NAND Flash controller sections in this document.
