Vybrid MVF62NN151CMK40 SNVS_LP current consumption

Is there any way of minimising the current consumption of the SNVS_LP module when only using the real time clock?


We would like to use a super capacitor to maintain the real time clock when the vybrid processor is powered down, but at the moment, the low power SNVS consumes about 14uA in this state.   I think most of the SNVS_LP features are set at their default values, so are there any features that can be turned off to considerably reduce the 14uA current consumption? Ideally we would like to get it below 1uA which is more in line with a dedicated real time clock chip.
