I wanted to calculate the sample time for extended mode. as written in the manual in the extended mode the SAMPCON will stay high for SHI high time (basically controlled by this signal). what I am not understanding is what SHI signal is? it says that SHI source can be selected using SHSx bits which is from ADC12SC bit, TImer_A Output Unit 1 , The Timer_B Output Unit 0, and Timer_B Output Unit1. does this mean if I choose SHS bit to be Timer_A Ouput Unit1 my SHI signal is identical to this?
and also what is the ADC12SC bit doing there how could it be a source.
