Thanks for that, I wonder how many switches out there have it enabled inadvertently, because of a mistake by the manufacturer?
By the way, Some of the Broadcom chips have an integrated 8051, with on-chip ROM firmware. There are leaked datasheets floating around somewhere as well. If someone has the time to dump the on-chip ROM, it would be interesting to see what's in there.
Note, some of the pins marked NC in the datasheet are in fact the 8051 UART TX/RX lines.
