   • If using external memory, configure the memory access settings as per the datasheet.
   • The internal SRAM can be used for temporary data storage.

6. DMA Setup:

   • Enable DMA if required for high-speed data transfer.
   • Configure DMA channels and interrupts as needed.

7. Interrupt Handling:

   • Set up interrupt handling routines to manage USB events and data transfers.
   • Enable and mask interrupts as necessary.

8. Firmware/Driver Installation:

   • Install the appropriate firmware or drivers for the host controller.
   • Ensure the firmware is compatible with the operating system and application.

9. Testing:

   • Test the USB connection with various devices to ensure compatibility and reliability.
   • Monitor power consumption and temperature to ensure they remain within safe limits.

10. Documentation:

    • Refer to the detailed datasheet and application notes for more advanced configurations and troubleshooting tips.
