Example :

QTR 0xA 3  !! Pops the queue, and copies the data in the 
           !! both banks of register 0xA (BS4 = 3)
		   
QTR 0xB 2  !! Pops the queue, and copies the data to the 
           !! high bank of register 0xB (BS4 = 2)
		   
QTR 0xC 1  !! Pops the queue, and copies the data to the 
           !! low bank of register 0xC (Bs4 = 1)
		   
QTR 0xD 0  !! Pops the queue, but, does not copy the data 
           !! to register 0xD (BS4 = 0)
