Hictop 3DP11/12 Controller

I Have a Hictop Controller connector diagram below for the MKS.3 controller.

Digital output Analog input
┌───┬───┬───┬───┐
│ D12 │ D11│A12 │ A11 │
├───┼───┼───┼───┤
│GND│GND│GND│GND│
├───┼───┼───┼───┤
│ +5V │+ 5V │+5V │+5V │
└───┴───┴───┴───┘

What I do not know is what pins are associated with A11, A12 and what pins are associated with D11, D12
Any help would be appreciated. Would be nice to know how to use these inputs and outputs.
