Question regarding using multiple timer interrupts

Hi Everyone,

I have try to setup some timers with interrupt routines to handle the output result.  But the timer didn't work as expected,   With a single interrupt it works fine(Timer0_A0_ISR), but when I try to add more timers with interrupt into the code, the new interrupt didn't work, even the original single one didn't work as well.   Is there anything I should be aware of?

The code is running based on MSP430FR6989, CCS6.0 environment.

Thanks ahead!
