[83] TWIS: STOPPED event occurs twice if the STOP task is triggered during a transaction

This anomaly applies to IC Rev. Engineering B, build codes QFAA-BA0, CHAA-AA0.


STOPPED event is set after clearing it.


The STOP task is triggered during a transaction.


STOPPED event occurs twice: When the STOP task is fired and when the master issues a stop condition on the bus. This could provoke an extra interrupt or a failure in the TWIS driver.


The last STOPPED event must be accounted for in software.
