13 Boot Code
Boot-code copies predefined USB descriptors to shared RAM. It then checks if EEPROM is present on the I
2
C port.
If a valid signature is found, boot-code reads in the data-type field to determine if the data section is application code
or USB device information. If it is application code, boot-code downloads the code to external data-space. Once code
is loaded and the checksum is correct, boot-code then releases control to the application code. If the data contain
USB device information, boot-code reads in the data and, if the checksum is correct, copies it to hub registers and
the embedded function device descriptor. Otherwise, it restores predefined settings to hub registers and the device
descriptor.
Boot-code waits for the firmware to be downloaded from the host. Once the firmware is loaded, boot-code disconnects
from the USB and releases control to the firmware. For more information, see application notes for this product.
