Microcontroller Control
From PinballControllers Wiki
For systems in which a P-ROC needs to be controlled by microcontroller or a control system that doesn't have USB, the P-ROC provides an asynchronous 8-bit control bus accessible via a 16-pin ribbon cable header. This bus contains:
- 4 data bits
- 4 control bits
- read
- write
- empty
- full
Data can be written into the P-ROC when full is low and read from the P-ROC when empty is low. For more details, refer the the P-ROC FPGA Specifications on the P-ROC Documentation Page.
