6. Current with oscillator running, all analogue cells active, SPI communication and NXT pulses applied. No floating inputs. Guaranteed by

design.

7. Current with all analogue cells in power down. Logic is powered but no clocks running. All outputs unloaded, no inputs floating.

8. Not valid for pins with internal Pulldown resistor
