Hardware Interface
4.3 LAN Interface
iChip Plus directly interfaces an Ethernet LAN MAC/PHY device on its 16-bit local
BUS. Currently iChip Plus supports the Crystal LAN CS8900A Ethernet controllers for
10BaseT and SMSC LAN91C111 and ASIX AX88796L Ethernet controllers for
10/100BaseT.
4.4 Serial Modem Interface
iChip Plus 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:

Table 4-2 Modem 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 Plus operates in Serial
mode). When iChip Plus operates in Parallel mode, the modem interface baud rate must
be preprogrammed.
All serial modem input signals (RXDM, -DSRM, -CTSM, -CDM) are 5V tolerant.
iChip Plus does not provide a Ring Indicator input signal.
