2FCCs Project
This section describes the hardware set-up and the software modules of the 2FCCs project.
There are two example hardware configurations for the 2FCCs project. The first uses two MSC8101ADS
boards, so FCC1 is not available and must be disabled in the software project configuration file. The
second set-up involves both an MSC8101ADS and an E1 communication (ECOM) board, which is a
peripheral extension board designed to connect to the MPC8260ADS.
Ethernet transceiver.
As Figure 3 shows, the two-MSC8101ADS set-up is defined as follows:
• Crystal = 16,384 MHz; MODCLK40 (yielding SC140 core/CPM/60x-compatible system bus speeds of
• Two PCs with suitable ports (PCI or parallel) for JTAG probes to download, tune, and debug the
• A JTAG probe for the MSC8101ADS (Macraigor Systems LLC’s OCDemon™ Wiggler)
• One twisted Ethernet cable or one Ethernet switch and two straight Ethernet cables
