TPL0102-100: How to use TPL0102 WRA WRB as a individual variable Resistor for application

Hello TI,

I am Using TPL0102 Digital POT in my application circuit 

1.Is it possible to use WRA and WRB resistor individually in TPL0102...? if yes please share some reference for development

2.TPL0102 WRA work when i use 0x00 and WRB work when i use 0x01 for instruction, how to use both resistor parallel for different application ...?

3.I want to use both resistor for different application, can i use TPL0102 like this ...?

i am sharing my Schematic circuit and application code 

#include <Wire.h>

void setup() {
Wire.begin(); // join i2c bus (address optional for master)
Serial.begin(9600);
}

//byte val = 0;

void loop() {
Wire.beginTransmission(0x50); // transmit to device address 0x50
// device address is specified in datasheet
Wire.write(byte(0x00)); // sends instruction byte WRA
Wire.write(byte(0x01)); // sends potentiometer value byte
Wire.endTransmission(); // stop transmitting

//val++; // increment value
// if (val == 256) { // if reached 255th position (max)
// val = 0; // start over from lowest value
//}

//delay(500);
}
