K64 Max current on USB VREG VOUT33

I plan to use the Vreg to power the K64 and few peripherals (approx 85mA). The 5V input  to Vreg in is always available (separate from USB )

Questions on USB VREG:

1. Datasheet for MK64FN1M0VMD12 Max load current for VOUT33 to be 120mA. Please clarify if this 120mA is additional to the internal consumption of the chip (Max 42 mA as per datasheet).

2. Does the  USB VREG turn on automatically? I plan to use it to power the K64 MCU

Thanks

Ashok
