Configuration and Operation
Figure 2-8 shows how the UART and IrDA circuits are connected.
2.3.10
The ADS is equipped with a Cirrus Logic CS8900A Crystal LAN ISA Ethernet Controller. The CS8900A
has a 10BaseT transmit and receive filters. The interface can operate in interrupt-driven mode and perform
DMA transfers. The Chip-select function is controlled by CPLD logic. Figure 2-9 shows the Ethernet
interface.
