I don't find document defined below pin location

1) I don't find document defined below pin location.  I don't see this information from pin connection guide line and adc convert ug

     ADC[1..2]IN[1..16];  ADC_VREF; ANAIN[1] ; ANAIN[2]

2) what's the difference between ADC[1..2]IN[1..16] and ANAIN[1]?

Hi Xiaoqiang

For Q1, if we refer to Table 6 of https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf

There is description for ADC[1..2]IN[1..16], ANAIN[1], ANAIN[2] and ADC_VREF.

For Q2, Max10 devices support up to 18 channels for analog measurement: 16 dual function channels and two dedicated analog input channels in dual ADC devices.

ANAIN[1] is the dedicated single-ended analog input pin for ADC1 while ANAIN[2] is for ADC2.

Whereas ADC[1..2]IN[1..16] are the multi-purpose pins that support single-ended analog input. When they are not used as analog input pins, these pins can be used as any other digital I/O pins.

Thanks.

Eng Wei
