Clock status monitor Register
| XTL12M_STB | XTL12M clock source stable flag 1 = External Crystal clock is stable 0 = External Crystal clock is not stable or not enable |
| PLL_STB | PLL clock source stable flag 1 = PLL clock is stable 0 = PLL clock is not stable or not enable |
| OSC10K_STB | OSC10K clock source stable flag 1 = OSC10K clock is stable 0 = OSC10K clock is not stable or not enable |
| OSC22M_STB | OSC22M clock source stable flag 1 = OSC22M clock is stable 0 = OSC22M clock is not stable or not enable |
| CLK_SW_FAIL | Clock switch fail flag 1 = Clock switch fail 0 = Clock switch success This bit will be set when target switch clock source is not stable. Write 1 to clear this bit to zero. |
