Note 6: ILOAD includes the pull-up resistor current via pin VPU
Note 7: The minimum voltage in Suspend mode is 2.7V.
Note 8: Not tested in production, value based on characterization.
Note 9: Excludes any current from load and VPU current to the 1.5kΩ resistor.
Note 10: Includes current between Vpu and the 1.5k internal pull-up resistor.
Note 11: When VCCIO < 2.7V, minimum value for VREGTH = 2.0V for supply present condition.
