Note:

CMOSen = 0 must only be used when V_CC is between 2.0V and 5.5V and the host is running on a lower supply voltage than the client. In this mode, the input buffers are referenced to an internal supply and V_IL and V_IH levels are independent of the external V_CC supply over this range. For voltages lower than 2.0V, CMOSen must always be set to ‘1’.
The lowest system current will be achieved if the inputs are driven to V_CC or allowed to be pulled up to V_CC by the pull-up resistors on the signal lines.
Applies to all commands where an EEPROM write does not occur.
Applies to all commands where an EEPROM write occurs. This includes Write, Lock, GenKey, Counter(Increment).
This condition is characterized but not production tested.
When coming out of Sleep mode when CMOSen=0, the initial input thresholds are V_ILS/V_IHS. When the device is awake, the thresholds will transition to V_IL0/ V_IH0.
