2.11.1 TIMEOUT Bit Field in the TWIn.MCTRLA Register is Corrupted

The SMBus TIMEOUT bit field in the TWIn.MCTRLA register is corrupted, resulting in the bus state not correctly entering IDLE after a timeout.

Work Around

To ensure correct operation when initializing the TWI, the BUSSTATE must be controlled from the software by forcing it to IDLE (writing BUSSTATE in TWIn.MSTATUS to 0x1).
