Timer1 resolution and minimum number of clock cycles to execute.

Other Parts Discussed in Thread: TMS320F28021

Hello All,

For a certain application of ours, we are using TMS320F28021 MCU.  In that, i want to to use Timer1 for triggering at certain events. But what i have observed from CCS, in debug mode, is that it takes a minimum of 99 cycles to exit from the timer (when local variables are there and body statement) and minimum 33 cycles when it is empty. After that it takes the time which is set in the PRD to execute the timer1 ISR again. 

For me, i want to a minimum of 30th event to trigger (30 cycles) to make an exit, so is it possible?? and what is its resolution and the minimum number of cycles to exit from the timer1.

Thanks
