| description: |
| The Microchip PIT64B is a 64-bit periodic interval timer used in |
| several modern Microchip ARM SoCs including SAM9X60, SAM9X7 and |
| SAMA7D65 families. It provides extended timing range, flexible |
| clock selection and supports both periodic and one-shot interrupt |
| generation modes. |
