[30] PWM: False SEQEND[0] and SEQEND[1] events are generated

This anomaly applies to IC Rev. Engineering A, build codes SICA-BAA.

Symptoms

False SEQEND[0] and SEQEND[1] events are being generated.

Conditions

Any of the LOOPSDONE_SEQSTARTn shortcuts are enabled. LOOP register is nonzero and SEQ[1].CNT is set to 1.

Consequences

SEQEND[0] and SEQEND[1] events might falsely trigger other tasks if they are routed through the PPI.

Workaround

Avoid using the LOOPSDONE_SEQSTARTn shortcuts when the LOOP register is nonzero and SEQ[1].CNT is set to 1.
