Zusammenfassung:An apparatus is provided that includes a device interface including port(s) coupled to and defining respective data channel(s) for respective peripheral(s). The device interface also includes boot control logic and a volatile buffer memory, and a volatile configuration memory. The apparatus also includes a non-volatile device storage memory including a contiguous memory block configured to store boot code with a boot set including a configuration routine. The boot control logic is configured to execute boot code including the boot set at power up or reset of the apparatus. The boot set includes a read of data from the device storage memory to the buffer memory, and a write of the data from the buffer memory to configuration memory to initialize the apparatus or a port, with the data being read from a portion of the device storage memory outside the contiguous memory block configured to store the boot code.
