I2C in CallBack mode either using a timer or a clock module

Hello Everyone!

MSP430f5438A

I want to use I2C in callback mode either using a timer or a clock module to do 5 I2C_transfer(). 

When I use it in a task it works fine but in timer and clock module it gives error.

{module#32}: line 289: error {id:0xda40000, args:[0x7662, 0x7666]}
xdc.runtime.Error.raise: terminating execution

(can you also tell how to decode this error message)

and here is the .cfg file.

6663.tiRTOS.cfg

Can anyone help me out to resolve this issue.

Thanks!
