APPLICATIONS
Figures 6 and 7 illustrate typical applications of the
MB86703.
In Figure 6, the chip is combined with Fujitsu’s
MB86964 Ethernet controller with Twisted Pair trans-
ceiver to form a highly integrated Plug and Play ready
Ethernet adapter card. The MB86964 uses one I/O
chip select and one interrupt. A memory chip select is
used to address the boot PROM or ash memory.
A high-speed serial line to Ethernet bridge application
is illustrated in Figure 7. In this application the
MB86703 is programmed to support four logical
devices (three are used) and to support DMA channel
conguration. Logical Device 0 provides interrupt,
DMA and I/O chip select support for the USART
controller. Logical Devices 1 and 2 provide interrupt
and I/O chip select support for the modem and
MB86964 Ethernet controller. By assigning separate
logical devices to each function, each can be activated
or deactivated independently and the driver can be par-
titioned into separate modules,allowing each to be writ-
ten and debugged independent of the others.
