MSP430F2272: MSP430F2272: I2C Bus Activity Prevention

Part Number: MSP430F2272

Hello MSP430 team,

I have an MSP4302272 on a design which is initializing some components on the board, does some I2C writes, and then is supposed to go into I2C slave mode.

I am also trying to run some tests that are done over I2C on other system components and have been unable to get any real results. However, a HW fix which removed the I2C lines going into the MSP430 of course allows for results to be received.

In code, the MSP430 should be in slave mode, so I am confused that there is any issue when running this test over I2C since my understanding is that if the MSP430 is a slave, it should not be interfering with the bus if it is not addressed.

My question is: Is there a command or line of code I can write to the MSP430 to accomplish the same thing as essentially disconnecting its I2C pins from the bus?
