Arduino Uno timer2 with SPI

Hi, I have a question about using a timer2 interrupt while also using an SPI connection with digital pins Pins 10-13.

Currently I believe I'm preforming a 2ms timer interrupt set up with the following code and I'm wondering if the PWM on pin11 will mess with the module I have connected via the SPI connection here:

void interruptSetup(){ .
TCCR2A = 0x02;
TCCR2B = 0x06;
OCR2A = 0X7C;
TIMSK2 = 0x02;
sei();
}

Will this timer interrupt prevent my SPI from working properly, or do I probably have an issue elsewhere?

Thanks for your help!

So far you haven't stated that you have an issue. You have only asked questions . Nowhere does it say :
"I am having an issue ...this doesn't work....or when I try to do this ..this happens, or my code isn't working..or my interrupt is not working etc etc etc.."

Let me clarify:

Currently my interrupt is working, but my microSD card module (attached via an SPI connection) isn't working when I run the below interrupt with it. Thus I'm trying to figure out if the cause might be due to the PWM signal that is produced on pin Digital pin11 when using a timmer2 interrupt.

Thanks

void interruptSetup(){     .
 // TCCR2A = 0x02; 
//  TCCR2B = 0x06;  
 // OCR2A = 0X7C;  
 // TIMSK2 = 0x02; 
//  sei();    
}

RUN THIS.
IF YOUR SD CARD WORKS THEN THE ANSWER IS YES (IT IS INTERFERING).
That's simple enough isn't it ?
