Table 7.8 I/O Buffer Characteristics VDDVARIO=1.8V +/- 10%
This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down
and pull-up resistors add +/- 50uA per-pin (typical). When operating at reduced VDDVARIO
voltage levels (less than 3.0V), do not rely on internal pull-up and pull-down resistors to
determine signal state. Refer to the individual signal descriptions in
Description and Configuration
This is the total V
the number of pins driven to V
are driven to the maximum operational limit for V
VDDVARIO), the per-pin input leakage is the maximum input leakage current divided by
10.
