50uA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-
ups are always enabled.
Note:
50uA (typical) internal pull-down. Unless otherwise noted in the pin description, internal
pull-downs are always enabled.

Sink and source capabilities are dependant on the VDDIO voltage. Refer to
"Absolute Maximum Ratings*," on page 63
for additional buffer information.
Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on
internal resistors to drive signals external to the device. When connected to a load
that must be pulled high, an external resistor must be added.
Internal pull-down resistors prevent unconnected inputs from floating. Do not rely
on internal resistors to drive signals external to the device. When connected to a
load that must be pulled low, an external resistor must be added.
