| KNOWN ISSUES: |
| Cube is occasionally flickering to ~60Hz. Need to figure out why. |
| Interrupts dont seem to be preempting properly. Not sure why. |
| >= 400MHz I2C1 doesn't seem to work very well the controllers |

| PERIPHERAL USAGE: |
| SPI1 - Used by the cube code to send data to the ube |
| SPI1 - Used by the cube code to send data to the cube |
| SPI4 - Unused |
| I2C1 - Used by the controller code |
| TIMER2 - Used by PWM2 |
| TIMER4 - Used by the cube code for the overlay rotation interrupt |
| TIMER4 - Used by the cube code for the overlay rotation interrupt / controllers |
| TIMER5 - Used by the cube code for the update layer interrupt |
| UART1 - Used by the cube code for reading in frame data |
| PWM2 - Generates a constant ~20MHz output, uses TIMER2 |
