MPC5XXX I2C Start signal issue

The start signal is not being generated on the I2C bus of MPC5XXX controller. There is no SDA high to low transition observed on the oscilloscope.

I have taken care about configuring the clock, enabling the I2C module, port settings( open drain, weak pull up ) etc that are required in the first place. I could see that the master and transmit bits are set inside the debugger.

Can someone help me find out what could be the reason for not getting a start condition ?
