Table 46: Pin Behavior during Configuration (Continued)
Table 47: Default I/O Standard Setting During Configuration (VCCO_2 = 2.5V)
The HSWAP pin itself has an pull-up resistor enabled during
configuration. However, the VCCO_0 supply voltage must
be applied before the pull-up resistor becomes active. If the
VCCO_0 supply ramps after the VCCO_2 power supply, do

Gray shaded cells represent pins that are in a high-impedance state (Hi-Z, floating) during configuration. These pins have an optional
internal pull-up resistor to their respective V
Yellow shaded cells represent pins with an internal pull-up resistor to its respective voltage supply rail that is active during
configuration, regardless of the HSWAP pin.
Note that dual-purpose outputs are supplied by V
