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

This anomaly applies to IC Rev. Revision 2, build codes CIAA-Ex0, QFAA-Ex0, QFAB-Ex0.

It was inherited from the previous IC revision Revision 1.


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.
