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

This anomaly applies to IC Rev. Rev 1, build codes QKAA-D00.

It was inherited from the previous IC revision Engineering D.

Domains

Application

Symptoms

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