Minimize the time external reset is active.
39.2.1.4 SERCOM
1 - In USART autobaud mode, missing stop bits are not recognized as inconsistent sync
(ISF) or framing (FERR) errors. Errata reference: 13852
Fix/Workaround:
None
2 - If the SERCOM is enabled in SPI mode with SSL detection enabled (CTRLB.SSDE) and
CTRLB.RXEN=1, an erroneous slave select low interrupt (INTFLAG.SSL) can be generated.
Errata reference: 13369
Fix/Workaround:
Enable the SERCOM first with CTRLB.RXEN=0. In a subsequent write, set CTRLB.RXEN=1.
39.2.1.5 TC
1 - Spurious TC overflow and Match/Capture events may occur. Errata reference: 13268
Fix/Workaround:
Do not use the TC overflow and Match/Capture events. Use the corresponding Interrupts instead.
39.2.1.6 TCC
1 - In RAMP 2 mode with Fault keep, qualified and restart: Errata reference: 13262
If a fault occurred at the end of the period during the qualified state, the switch to the next ramp can
have two restarts.
Fix/Workaround:
Avoid faults few cycles before the end or the beginning of a ramp.
