Pin sharing between ADC channel and KBI

I am using a S9KEAZN custom board and I would like to know if I can pin share between two peripheral ADC and KBI. I try adding an extra channel in my ADC but unfortunately I am using the same pin as a KBI for waking up and putting the CPU to sleep. Is there a way I can use the same pin in two different peripherals?

Also when I try doing this, the PE component ADC throws an error stating that I cannot add a channel since the pin is already used by KBI. Is there a work around for this. I am not too enthused about redesigning on the hardware.

Hi SAIPRIYA,

I'm not very clear of your applictaion. Some time we share the pin between digital functions, but it's rarely share between digital and analog functions.
