4 Hardware Interface
iChip Plus CO561AD-D interfaces between a host CPU and a modem.
4.1 Host Interface
The host interface is a serial DTE interface. Speeds of 2400, 4800, 9600, 19200,
38400, 57600 and 115200 bps are supported in the following data format:
Note: 1) When hardware flow control is enabled, the iChip Plus transmitter will add
4.2 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 10BaseT Ethernet
controller.
4.3 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 and 115200 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 Plus operates in Serial
mode). When iChip Plus operates in Parallel mode, the modem interface baud rate
must be preprogrammed.
iChip Plus does not provide a Ring Indicator input signal.
