Functional Description
iChip & iChip LAN Datasheet 3-3
3.2.6 Local Bus Connection to Ethernet Controller
iChip LAN CO561AD-L directly supports a Crystal LAN CS8900A IEEE 802.3 Ethernet
Controller in 16-bit memory mode. Interrupt and DMA request are directly connected to
dedicated inputs. A small PLD or discrete logic is required to generate the
MEMRD#/MEMWE# and IORD#/IOWR# signals that form iChip’s RD# and WR#
signals to simulate memory, IO and DMA accesses. See section "6.4 Reference Design
for Embedded LAN Using iChip LAN CO561AD-L".
3.2.7 Hardware and Software Flow Control
Hardware flow control is supported between the host CPU and iChip. Hardware flow
control is also provided between the iChip CO561AD-S and the modem. Flow control is
programmed via the AT+iFLW command. The default flow control methods are set to
Wait/Continue software flow control between iChip and host, and no flow control
between iChip and modem.
The hardware flow control method frees the host CPU from monitoring and handling the
software flow control. The host can program iChip to either use hardware flow control or
to use Wait/Continue software flow control between the iChip and the host CPU. The
flow control mechanism is based on the RTS/CTS signals.
Flow control between iChip and the Modem can be individually programmed to hardware
flow control or no flow control.
The Crystal Ethernet Controller CS8900A provides sufficient buffers to support the
packet flow control on TCP/IP level between iChip LAN and the Ethernet LAN.
