    Holly crap, yeah, that make sense indeed. Yet another stupidity from Microchip

    So my example will need some changes...
    Code:
            '
            '       Configure ADC
            '       =============
            ANCON0  VAR BYTE EXT    ' not included in PBP2.50c
            ANCON1  VAR BYTE EXT    ' not included in PBP2.50c
            
            WDTCON.4 = 1    ' Switch to Alternate SFR
            ANCON0 = %10011110
                   '  -xx------ Not Implemented
                   '  1--1111-- AN7, & AN<4:1> = Digital
                   '  -------0- AN0 = Analog
                   
            ANCON1 = %11111111
                   '  11111111- AN<15:10> = Digital
                                         
            WDTCON.4 = 0    ' Back to Default SFR
    or
    Code:
            '
            '       Configure ADC
            '       =============
            WDTCON.4 = 1    ' Switch to Alternate SFR
            
            ADCON1 = %10011110  ' alternate ANCON0
                   '  -xx------ Not Implemented
                   '  1--1111-- AN7, & AN<4:1> = Digital
                   '  -------0- AN0 = Analog
                   
            ADCON0 = %11111111  ' alternate ANCON1 
                   '  11111111- AN<15:10> = Digital
                                         
            WDTCON.4 = 0    ' Back to Default SFR
    By far, i prefer the first, easier to read

    However, yours work.. keep it like that. If it's not broken, don't fix it!

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
