Using GPIO for AD converter

Question

Hi, 
 I'm using MCU RL78/L13 for my development. 
 From datasheet I could see that the AD converter functionality using PINs 56-64. 
 But I would like to know is it possible to use other GPIO (like Pin 50-55) for this perpose. 
 Thank you very much

All pin functions are listed on section 2.1.1 for 64-pin and 2.1.2 for 80-pin devices.

 If a pin is not listed as analog input, it cannot be used by A/D converter.

Hello ThiVu, 
 Only the pins that have the alternative function AINxx can be used as inputs of the ADC, in 64-pin package there are pins 56-64, in 80-pin package there are pins 69-80 only. 
 Kind regards,
