NT3H2211 power consumption from I2C side

I'm working on a very-low-power device with number of sensors/ICs on I2C bus and I want to add some functionality to transmit collected events via NFC. NT3H2211 looks quite suitable, but I can't find the answers to several questions:

 

1. What the supply current of NT3H2211 powered from VCC (1.8Volts) only (with no I2C communications at all)?

2. Will NT3H2211 steal power from I2C bus (via I2C pull-up resistors) if its VCC remains floating and no field present? How much?

 

3. What the supply current of NT3H2211 powered from VCC (1.8Volts) only (I2C used by other devices on I2C bus, but not NT3H2211)?

 

The datasheet and googling not really helped, so I look for someone who can directly try and measure these paramefers.
