Depending on the type of firmware used as specified in the header block of the external I
2
C EEPROM, the
boot code can determine:
• Whether to perform connection to the USB host for enumeration before downloading the firmware into the
internal code RAM
• Whether to remain disconnected during the firmware code downloading process. In this case, the
firmware, once in charge, assumes the responsibility of performing the connect and enumeration tasks.
For details on how to specify the header block of the external I
2
C EEPROM, booting, and enumeration options,
see the TUSB6250 Bootcode Application Note application report (SLLA126).
