ADRESH and ADRESL are in bank0 and bank1 respectively. May be you try to

>   configure ADCON0 = 01000001 (fosc/8, channel0, AD operating )
>   set Go/done bit
>   wait for ad conversion to complete
>   read result register pairs: ADRESH & ADRESL
>
>   My problem: the contents of ADRESH is the same with ADRESL (
> LSB 8 bites for right justified or first MSB 2 bites for left justified )
>   How to read correctly all 10 bites ?
