Card side supply voltage.
The enable time is from power-up of V
Idle time is from when SDAn and SCLn are HIGH after enable time has been met.
I
The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V
Guaranteed by design, not production tested.
