[183] PWM: False SEQEND[0] and SEQEND[1] events

This anomaly applies to IC Rev. Rev 2, build codes QFAA-E00, CIAA-E00, QFAB-E00.

It was inherited from the previous IC revision Rev 1.

Symptoms

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

Conditions

Any of the LOOPSDONE_SEQSTARTn shortcuts are enabled. LOOP register is non-zero and sequence 1 is one value long.

Consequences

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

Workaround

Avoid using the LOOPSDONE_SEQSTARTn shortcuts, when LOOP register is non-zero and sequence 1 is one value long.
