Battery monitor for the nRF51822

[andrew sauter]

Does nRF51822 have battery monitor?

pg 45 of datasheet says specifies "Absolute error when used for battery measurement" at:

Internal reference, input from VDD/3 10 bit setting

but I do not understand what that means, is there separate ADC config document?
