(1)

Iload includes the pullup resistor current via Vpu(3.3).

(2)

In suspend mode, the typical voltage is 2.8 V (see XX).

(3)

Maximum value is characterized only, not tested in production.

(4)

Excluding any load current and Vpu(3.3)/Vsw source current to the 1.5-kΩ and 15-kΩ pullup and pulldown resistors (200 µA typ)

(5)

When VCC(I/O) < 2.7 V, the minimum value for Vreg(3.3)th (present) is 2 V.
