There is a lot more functionality here than was used in any of the three mappers that used it.

Mask: $E103
  Write $4103: [.... ...C] - Set/Clear Increment Mode
  Write $4101: [.... ...V] - Set/Clear Invert Mode. Also affects io2 and o3.

                             When clear, io2 relays i0. When set, io2 relays i1.
                             o3 is io2 OR D5 continuously.

                             If something externally overpowers io2, then:
                             When V is clear, o3 is i0 OR D5.
                             When V is set, o3 is io2 OR D5.

  Write $4102: [..RR .PPP] - D[5,4] -> R[5,4]. D[2,1,0] -> P[2,1,0]
                             P3 XOR V -> P3.
  Write $4100: [.... ....] - If Increment Mode is set, R[3,2,1,0] += 1
                             Otherwise, P[3,2,1,0] XOR V -> R[3,2,1,0]
Mask: $E100
  Read $4100:  [..RR .RRR] - R[5,4] XOR V -> D[5,4]. R[2,1,0] -> D[2,1,0]
Mask: $8000
  Write $8000: [.... ....] - R[3,2,1,0] -> Q[3,2,1,0]. R4 XOR V -> Q4.
