CC2530, best method to wait on signal?

Hi,

I want the program to wait for atmost 2ms until the pin becomes high. 

//initialise timer for 2ms. on time out set TIMEOUT = true

while(TIMEOUT){

//check value of signal. if (high) {break} else {continue}

}

But executing the while loop every time will be unnecessary wastage of resources.

I would like to know whether it is possible to implement this with interrupts using higher level abstraction methods.
