| 12 | +description: |
| 13 | + The Clock Pulse Generator (CPG) generates core clocks for the SoC. It |
| 14 | + includes PLLs, and fixed and variable ratio dividers. |
| 15 | + |
| 16 | + The CPG may also provide a Clock Domain for SoC devices, in combination with |
| 17 | + the CPG Module Stop (MSTP) Clocks. |
