MSP430FR5969: Using same timer for sourcing and interrupt

Part Number:MSP430FR5969

Hi,

     I am trying to use the same timer for sourcing the ADC and then running UART int he timer interrupt.But it is not working.If I use two timer interrupts then also no results .

Is it possible to use it in this way.I am not sure about how to go about  it.I am suppose to sample the ADC for 100ms in 1 second and print the data on uart every 10 seconds.

It would be really great if somebody could help me in clearing this concept or give a suggestion for implementation.

Thanks 

Regards
