ADC mux on K20

Hi All,

 

I have a K20DX512 device configured and reading accurately from ADC0.

 

However, I would like to read multiple channels at once, or a group of channels (i.e. x4) and interupt only when the four ADCs have succesful conversions in place.

 

I am guessing this is done by assigning the required ADC channels to a ADC MUX function? I am struggling to source much documentation on this, the data sheet seems only to refer to the MUXSEL bit.

 

Can anybody point me in the direction of assigning a channel 'set' to a ADC MUX mapping and how to configure for this process. Any links to documentation, etc would be gerat.

 

Thanks in advance,

 

K
