ADC pin on which nrf51822 provides voltage to calculate battery percentage

[Sachin bejgamwar]

Hello everyone ,

                We are able to read out ADC values(if i connect battery positive externally on ADC pins). i wanted to know if there is internal connection provided to any of the adc pin from which we are able to read supply voltage ? is there is any provision made for that in hardware of NRF51822?
