6.5 HPI Bus Interface
6.6 LAN/WiFi Interface
iChip directly interfaces an Ethernet LAN PHY device on its 8-bit local bus. Currently iChip
supports the Davicom DM9161A Ethernet PHY for 10/100BaseT. For Wireless LAN
applications, iChip supports a CF WiFi card based on the Marvell 88W8686 802.11b/g WiFi
chipset.
6.7 Serial Modem Interface
iChip includes a dedicated port to interface a serial modem. The modem interface is a serial
DCE interface. Speeds of 2400, 4800, 9600, 19200, 38400, 57600, 115200 and 230400 bps
are supported in the following data format:
Actual baud rate may be preprogrammed or dynamically defined as equal to the auto baud
rate detected on the serial host interface (when the iChip operates in serial mode). When
iChip operates in parallel mode, the modem interface baud rate must be preprogrammed.
