
Op2: Second operator 
Op3: Third operator 

Pr1: Priority of first operation

Pr2: Priority of second operation 
Pr3: Priority of third operation 
Qen 0
:
0: Reset value of AQ to 0
when En=0
1: Retain last value of AQ
when En=0
p: Number of decimals 
Range of values: 0, 1, 2, 3
Output AQ The output AQ is the result of the
equation formed from the operand
values and operators. AQ will be set
to 32767 if a divide by 0 or overflow
occurs, and -32768 if a negative
overflow (underflow) occurs.
