M1->Y:$78401,1 ; Input 5, J5 Pin 14

M2->Y:$78401,2 ; Input 2, J5 Pin 2

M3->Y:$78401,3 ; Input 6, J5 Pin 15

M4->Y:$78401,4 ; Input 3, J5 Pin 3

M5->Y:$78401,5 ; Input 7, J5 Pin 16

M6->Y:$78401,6 ; Input 4, J5 Pin 4

M7->Y:$78401,7 ; Input 8, J5 Pin 17

M8->X:$78401,0,8 ; I/O Direction Control

M8=$0 ; Set them as inputs

M9->Y:$78405,0,8 ; I/O Data Type Control

M9=$FF ; Set them as I/O (Not necessary since they are

always set to one)

M10->X:$78405,0,8 ; I/O Inversion Control

M10=$FF ; $FF represents 1 for high and 0 for low input

Outputs wiring

There are 4 outputs on the I/O connector, which can be used in sinking or sourcing mode. Since

these outputs share some circuitary, you can only use one type (sinking or sourcing) at a time.

The maximum current that these outputs can supply is 900mA on each output.
