The PLL configuration signals operate according to Table 11-10, which indicates the operation when the PLLs are not locked.
PLL Operation Mode | Stop Mode Low Power(1) | Stop Mode Fast Relock(1) | Idle Bypass |
---|---|---|---|
Mode Description | Output clocks stopped Lowest power standby | Output clocks stopped Fastest start-up time | Selects when PLL and HSDIVIDER bypass clocks are used |
PLL_CONFIGURATION2[0] PLL_IDLE | 0 | 0 | 1 |
PLL_CONFIGURATION2[6] PLL_LOWCURRSTBY | 1 | 0 | 1 |
When locked, the PLL output frequency (DCOCLK) is: Input frequency × 2 × M / (N + 1), where:
When the PLL_REGM bit field is set to 1, the PLL enters a MN-Bypass mode. The DCOCLK clock output goes low and remains low until the PLL exits MN-Bypass mode (by changing the PLL_REGM bit field to a value other than 0 or 1).
