Time-out (CTRLA.LOWTOUT) is disabled. When SCTRLA.LOWTOUT=0, the
GCLK_SERCOM_SLOW is not requested. Errata reference: 12003

Fix/Workaround:

To use the Master or Slave SCL low extend time-outs, enable the SCL Low Time-out
(CTRLA.LOWTOUT=1).

39.3.6 TCC

1 - With blanking enabled, a recoverable fault that occurs during the first increment of a
rising TCC is not blanked. Errata reference: 12519

Fix/Workaround:

None

2 - In Dual slope mode a Retrigger Event does not clear the TCC counter. Errata reference:
12354

Fix/Workaround:

None

3 - In two ramp mode, two events will be generated per cycle, one on each ramp’s end.
EVCTRL.CNTSEL.END cannot be used to identify the end of a double ramp cycle. Errata
reference: 12224

Fix/Workaround:

None

4 - If an input event triggered STOP action is performed at the same time as the counter
overflows, the first pulse width of the subsequent counter start can be altered with one
prescaled clock cycle. Errata reference: 12107

Fix/Workaround:

None

5 - When the RUNSTDBY bit is written after the TCC is enabled, the respective TCC APB bus
is stalled and the RUNDSTBY bit in the TCC CTRLA register is not enabled-protected. Errata
reference: 12477

Fix/Workaround:

None.

6 - TCC fault filtering on inverted fault is not working. Errata reference: 12512

Fix/Workaround:

Use only non-inverted faults.

7 - When waking up from the STANDBY power save mode, the SYNCBUSY.CTRLB and
SYNCBUSY.STATUS bits may be locked to 1. Errata reference: 12227

Fix/Workaround:
