Part Number: MSP432E411Y

Is it possible to reset only the I2C controller on the MSP432E411Y without resetting the entire MCU? If so- is there a documented procedure?

I think you want to close the I2C peripheral, you may need this:

Okay- is there an equivalent HW reset for I2C where the registers get reset, similar to a HW reset?

I think you want to set then clear the appropriate bit in SRI2C. [Ref TRM (SLAU723A) Sec 4.2.72]

There appears to be a function in driverlib for this, something like:

> SysCtlPeripheralReset(SYSCTL_PERIPH_I2C1);
