The low nibble sets the PRG-ROM banks both for the $6000-$7FFF and $8000-$9FFF CPU address ranges according to the following table:
Value written 0 1 2 3 4 5 6 7 8 9 A B C D E F ------------------------------------------------ $6000-$7FFF bank 1 1 3 3 5 5 7 7 9 9 B B D D F F $8000-$9FFF bank 0 A 2 A 4 A 6 A 8 8 A A C C E E
Or as table-less C code:
bank6 = value |1; bank8 = value &1 && ~value &8? 10: value &~1;
