intrr
Contains fields that indicate the PLL lock status.
| Module Instance | Base Address | Register Address |

Offset: 0xC
Access: RW
Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

intrr Fields
| Bit | Name | Description | Access | Reset |
|---|---|---|---|---|
| 11 | perpllfbslip | If 1, the Peripheral PLL feedback cycle has slipped (CLKOUT frequency too low). This does not mean the PLL has lost lock, but the quality of the clock has degraded. |
RW | 0x0 |
| 10 | mainpllfbslip | If 1, the Main PLL feedback cycle has slipped (CLKOUT frequency too low). This does not mean the PLL has lost lock, but the quality of the clock has degraded. |
RW | 0x0 |
| 9 | perpllrfslip | If 1, the Peripheral PLL reference cycle has slipped (CLKOUT frequency too high). This does not mean the PLL has lost lock, but the quality of the clock has degraded. |
RW | 0x0 |
| 8 | mainpllrfslip | If 1, the Main PLL reference cycle has slipped (CLKOUT frequency too high). This does not mean the PLL has lost lock, but the quality of the clock has degraded. |
RW | 0x0 |
| 3 | perplllost | If 1, the Peripheral PLL has lost lock at least once since this bit was cleared. If 0, the Peripheral PLL has not lost lock since this bit was cleared. |
RW | 0x0 |
| 2 | mainplllost | If 1, the Main PLL has lost lock at least once since this bit was cleared. If 0, the Main PLL has not lost lock since this bit was cleared. |
RW | 0x0 |
| 1 | perpllachieved | If 1, the Peripheral PLL has achieved lock at least once since this bit was cleared. If 0, the Peripheral PLL has not achieved lock since this bit was cleared. |
RW | 0x0 |
| 0 | mainpllachieved | If 1, the Main PLL has achieved lock at least once since this bit was cleared. If 0, the Main PLL has not achieved lock since this bit was cleared. |
RW | 0x0 |
