A conversion is divided into the following 27+ clock cycles:
12c (count up to Ch10) + 9c (sample) + 18c (conversion) = 39 cycles from start to end of conversion.
1c (count) + 9c (sample Ch15) + 18c (conversion Ch15) + 4c (in between) + 0c (count further to Ch10 is performed while
converting ch15) + 9c (sample) + 18c (conversion) = 59 cycles from start to end of both conversions.
