Powering Up the Board
A complete AT91CAP9A-DK system is powered through the AT91CAP-DKM motherboard via a stan-
dard ATX PC power supply.
The power control signal is connected to the SHDN signal, generated by the AT91CAP9 chip from the
AT91CAP9A-DKZ mezzanine board.
In case the AT91CAP-DKM motherboard has to be powered without a mezzanine or an AT91CAP9 chip
in place, the “Force Power ON” jumper J5 must be installed.
