R
using BGA packages, do not apply pressure to the device while activating the socket.
Doing so can damage the socket and/or the device.
12. Pin Breakout
The pin breakout area is used to monitor or apply signals to each of the DUT pins. Headers
can be soldered to the breakout area to use with certain types of oscilloscope probes, for
either connecting function generators or wiring pins to the pin breakout area. Clocks in the
pin breakout area that connect to the DUT clock pads are shown in
Table 1-6 .
13. User LEDs (Active-High)
There are eight active-high user LEDs on the board. Before configuration, the LEDs reflect
the status of the configuration mode switch. During configuration, the LEDs are in a high-
impedance condition. After configuration, the LEDs are available to the user and reflect the
status of pins
D0-D7 (corresponding to LED 0- LED 7). The LED assignments are shown in
Table 1-7
14. Program Switch
The active-low program switch, when pressed, grounds the program pin on the DUT.
