I2C repeated start bit needs 1ms delay. Why and is it right?

Hi, I am using a TQMAX6 module with IMX.6Dual core processor. My code kept crashing and restarting due to watchdog, but then again it was a repeated start until a delay of 1ms was introduced after the setting of RSTA bit in I2CR register of the I2C module.


There are 3 slaves connected. 


2. Temperature sensor

3. IOExpander


Is 1 ms too much of a delay? I found other sporadic crashes after this was done, although the initial crashing was solved after this. I am using a micrium OS, not LINUX. So please help me with an RTOS point of view.
