nector, if populated. Similarly, J156 can be used to enable the 5 V power going out on the samtec
connector, if populated.
The CTRL_4 line on the GPIF II interface is also used to enable or disable the on-board USB switch
for OTG power. This selection can be made on J100.
CTRL_4 is made.

As shown in
the GPIF II interface on the samtec connector. If 2 and 3 are connected, the CTRL_4 line routes to
the USB switch for OTG power control.
Reset Circuit
The FX3 device can either be reset from the external processor hooked up to the samtec connector
or from an on-board push button. This selection can be made on J72; see
Figure 2-8. Reset Circuit and Selection Headers
Based on the selection made on J72, either this reset signal goes to the FX3 device (pins 1 and 2
connected on J72) or a signal from the external processor resets the FX3 device (pins 2 and 3 con-
nected on J72).
I2C Interface
The I2C interface lines on the FX3 device come out to headers for probing and expansion, and also
connect to an on-board EEPROM device. The EEPROM address bits A2, A1, and A0 can be set
using the on-board dip switches on SW40.
