	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.

	help
	  Due to Anomaly 109 the first byte sent out by these peripherals is
	  sometimes wrong. This occurs when the system enters IDLE and stops the
	  64MHz clock at the same time as the peripheral that is using DMA is started.
	  This anomaly applies to IC revisions up to "3", the most recent one.
