1.3
A full set of schematics is provided in “Appendix A—Interface Schematics” on page 4. Figure 1-2 shows a
top-level interconnect of the major system components. It is followed by three top-level schematics that
show each major component’s functional blocks—Figure 1-3 shows the MPC8260, Figure 1-4 shows the
MPC7410, and Figure 1-5 shows the Tundra PowerPRO CA91L750. Figure 1-6 shows the shared SDRAM
that is controlled by the Tundra device and Figure 1-7 shows the boot FLASH.
Subsequent figures show the detailed interconnection to each of the functional blocks.
1.4
A complete listing of the initialization code and required header files is provided in “Appendix
B—Initialization Software” on page 25. This code should be held in the boot FLASH device and provides
all the initialization for both the PowerPRO and the MPC7410 and MPC8260 devices. The MPC8260 is
configured in hardware to be a configuration slave.
