UARTE power consumption clarification

Hi there,

We are developing our own uart driver, and need to understand the power consumption of the peripheral.

According to the product specification section electrical specifications, there seems to be a uart idle0 and idle1 state. 

Could you please clarify what the exact differences between the 2 are? From what clock is the peripheral running in idle0?

We are always running our HF clocks from the external 32MHz oscillator.
