hi,all
i am new to DSP and i am using eZdspF2812.I only know C, really bad at assemble language.
I have problem to update the period of a timer in EV continuously.

I know the period register has double-buffer shadow register. Suppose i want change the current
period value P1 to P2 in one period, and then change P2 to P3 in next period. My worry is that
P2 may not be in effect if the instructions are executed so fast that P1 is directly changed to
P3. How can i make sure that P2 is already in effect so i can change to P3?

thanks a lot.
eric
