Input Leakage current

Data sheet mentions LOW level input current ,high level input current off-state output current and input leakage current.All with a number of footnotes.

Now the HIGH and LOW level input currents are in the nA range , while the input leakage current is in the uA range.

I just wanted to know the sum of leakage currents in the case of using a pin as ADC input.


I've had several of my colleagues to read this particular section of the data sheet and none of them even gets a remote clue of what this all is supposed to mean.


This data was found in the LPC84x data sheet Ver 1.9 in table 15 on page 54-56 , but it also appeared in the LPC824 datasheet as I recall.
