15. Reset Switch (Active-Low)
The reset switch connects to the
INIT
pin on the DUT, allowing the user, after
configuration, to reset the logic within the DUT. Before and during configuration of the
DUT, the
INIT
pin has no function. After configuration, the
INIT
pin becomes a regular
I/O. When pressed, this switch grounds the
INIT
pin.
Table 1-8
shows the
INIT
pin locations for the available DUT package types.
16. DONE LED
The DONE LED indicates the status of the
DONE
pin on the DUT. This LED lights when
DONE
is high or if power is applied to the board without a part in the socket.
17. INIT LED
The INIT LED lights during initialization.
