4. Full functionality is guaranteed in VCC1 range, except USB transmitter specifications and GPIO output currents are guaranteed for VCC2 range.
5. Bench measurements taken under nominal operating conditions. Spec cannot be guaranteed at final test.
6. Total current cumulative across all Port pins, limited to minimize Power and Ground-Drop noise effects.
7. LVR is automatically disabled during suspend mode.
8. LVR will re-occur whenever VCC drops below VLVR. In suspend or with LVR disabled, BOR occurs whenever VCC drops below approximately 2.5V.
9. VREG specified for regulator enabled, idle conditions (i.e., no USB traffic), with load resistors listed. During USB transmits from the internal SIE, the VREG
output is not regulated, and should not be used as a general source of regulated voltage in that case. During receive of USB data, the VREG output drops
when D– is LOW due to internal series resistance of approximately 200Ω at the VREG pin.
10. In suspend mode, VREG is only valid if RPU is connected from D– to VREG pin, and RPD is connected from D– to ground.
