Appendix A: GPIO Lines
Pin assignment details for G24 KJAVA module GPIO lines are listed in the following tables.
Note:
1. GPIO 1-8 can be accessed via EVB switch S120.
2. Pin dedicated for Java Tool is marked yellow.
3. GPIO13 must not be grounded at power up.
4. If GPIO direction is input and line is not connected, its state will be defined according
Initial value.
5. If GPIO direction is output, "Floating" state is not available. Initial state depends on
initial configuration. This configuration can be controlled by Java GPIO API.
Y=Yes; N=No.
I = Input; O = Output; I/O = Input/Output.
