(4) Leaving HIPWR or PSEL open is an undetermined state and leads to unpredictable behavior. (5) These pins are high-z during a UVLO, reset, or in Sleep condition. (6) The pins were designed for less leakage, but testing only verifies that the leakage does not exceed 1 µA. (7) AUDIO is high-z during a UVLO, reset, or Device Sleep condition. (8) Protection is provided against a voltage greater than VDVDD being applied externally.
