SW-EK-TM4C129EXL: I2C Registers not writeable

Part Number: SW-EK-TM4C129EXL

I have searched all through these forums and not found any answers that have helped so far. 

I am using TI-RTOS 2.16_01_14 with TivaWare It seems that my calls to the I2C API functions are hit or miss for whether they actually write to the register. 

I am watching the registers while running and while stepping but the MDR never changes when Master Data Put is used. 

Code snippet:

// Set slave address and the write bit
I2CMasterSlaveAddrSet(pBusControl->peripheralMemoryMap, pBusControl->address, false);

// Set I2C Bus timeout
I2CMasterTimeoutSet(pBusControl->peripheralMemoryMap, 0xFF);

// Set the data byte to specify register to be read
I2CMasterDataPut(pBusControl->peripheralMemoryMap, pBusControl->transmitBuffer[0]);

Neither MCLKOCNT or MDR get set after those functions.

Anyone else have this issue and figure it out? Am i configuring something wrong? 

// Configure the GPIO Pin Mux for PA2
// for I2C8SCL

// Configure the GPIO Pin Mux for PA3
// for I2C8SDA
