Other Expansion I/O Connectors
In addition to the high-speed I/O paths, additional I/O signals and power connections are
available to support expansion cards plugged into the ML50
x
board. Fourteen I/O pins
from the general-purpose pushbutton switches and LEDs on the board are connected to
expansion connector J5. This permits additional I/Os to connect to the expansion
connector if the pushbutton switches and LEDs are not used. The connection also allows
the expansion card to utilize the pushbutton switches and LEDs on the board.
The expansion connector also allows the board's JTAG chain to be extended onto the
expansion card by setting jumper J21 accordingly.
The IIC bus on the board is also extended onto the expansion connector to allow additional
IIC devices to be bused together. If the expansion IIC bus is to be utilized, the user must
