5.2.5 Remote Internet Firmware Update
New firmware may be uploaded from a remote location using standard Internet protocols.
When iChip boots from a local flash device, it accepts firmware updates from a remote FTP
or HTTP server, as well as firmware uploads from a remote browser through iChip‘s web
server.
5.2.6 10/100BaseT Ethernet LAN Connection
iChip interfaces an Ethernet LAN PHY device via a dedicated, fully compliant MII or RMII
interface, as shown in Table 5-1. (
