Figure 2-10. PMODE [2:0] Signal Selection
Headers J96, J97, and J98 are used to select whether the PMODE [2:0] signals are set externally
(from the external processor) or on the board. PMODE_0, PMODE_1, and PMODE_2 on the FX3
device are connected to pin 2 of each header, J96, J97, and J98. Place a jumper on 1 and 2 to con-
trol the PMODE signals from the external processor, or on 2 and 3 to control the PMODE signals
from the dip switch SW25 on the board.
The PMODE [2:0] signals can be set either from the external processor or from the on-board dip
switch.
If the PMODE [2:0] signals are set to F1F or 1FF, the FX3 device will boot from the EEPROM con-
nected to the I2C interface. The EEPROM must contain the correct boot data for the FX3 device to
boot from it.
The PMODE [2:0] signals can be set on the dip switch SW25 as shown in
Figure
2-11.

If the bit is set towards the 'ON' text, the corresponding signal line is connected to ground. If the bit is
set towards the numeric text (away from the 'ON' text), the corresponding signal line is pulled high to
VIO1.
