AD21489 I2C NACK handling

I've been looking over the i2c documentation in the 21489 HW reference but can't find anything that talks about how you're supposed to handle NACKs on the I2C bus.

 

Right now I'm issuing and clearing the stop bit in TWIMCTL and clearing the FIFO using TWIMFIFOCTL.  However, when I do an i2c write with a bad address and then follow that with some normal transactions, the system hangs.

 

Thanks,

FM
