Is this the proper way to configure AN1 for analog input in the ADCON0 register. I’m not sure how to deal with unimplemented bits. Bit’s 5 and 4 are unimplemented does that mean when I write to the ADCON0 I put 00 in them? Or is this wrong?

PIC10F220 adcon0 register



Writing to ADCON0

Code: 
movlw     b'10000101'   ;CONFIG adc: AN1 Analog input
movwf     ADCON0
 

It does not matter what you actually write on the unimplemented bits, they will always be read as '0'. Your code should work. And it also should work if you put
Code: 
movlw     b'10110101'   ;CONFIG adc: AN1 Analog input

Ditto to bld's reply. Unimplemented bits are don't care when you write to them. Your config byte is correct.
