| help |
| Due to Anomaly 132 LF RC source may not start if restarted in certain |
| window after stopping (230 us to 330 us). Software reset also stops the |
| clock so if clock is initiated in certain window, the clock may also fail |
| to start at reboot. A delay is added before starting LF clock to ensure |
| that anomaly conditions are not met. Delay should be long enough to ensure |
| that clock is started later than 330 us after reset. If crystal oscillator |
| (XO) is used then low frequency clock initially starts with RC and then |
| seamlessly switches to XO which has much longer startup time thus, |
| depending on application, workaround may also need to be applied. |
| Additional drivers initialization increases initialization time and delay |
| may be shortened. Workaround is disabled by setting delay to 0. |
