2.5.1 Flush Non-Functional

Issuing a Flush by writing to the FLUSH bit in TWIn.MCTRLB can cause the TWI Host to be stuck in the Unknown bus state (see BUSSTATE in TWIn.MSTATUS).

Work Around

Disable and re-enable the Host using the ENABLE bit in TWIn.MCTRLA. An ordinary operation does not require the use of FLUSH.
