For technical details, please refer to the appended schematics:
sheet 5 (look for regulator
U6) and sheet 14 (look for regulator U10)

Host USB Port
The mini-AB connector J16 is connected directly to the AT91CAP9 chip. Please refer to the appended
schematics:
sheet 7 for in-depth details of its implementation.

FPGA Banking Allocations
As shown in the synoptic in
Figure 7-1 “AT91CAP9A-DKZ Mezzanine Block Diagram (see the complete
the Altera component has eight different IO banks. Each of these can be pow-
ered separately, thereby allowing different signaling standards of a system to be implemented in parallel.
Banking Allocations:
Banks 1, 2 and 3 = user IO going down to motherboard for user extension (PCI64, “Mistral”
connection, USB device interfaces)
Banks 4, 5 and 6 (partly) = PISMO-II extension connector
Bank 6 (partly) = leftovers allocated between the user I/O grid and EBI/FPGA connector
Bank 7 = EBI/FPGA connector
Bank 8 = AT91CAP9 connection via MPIO bus.
