D8
These bits do not affect the wiper register values.
D8: Reserved. Forced to “1”
R3HW: Resistor 3 Hardware Configuration Control bit
This bit forces Resistor 3 into the “shutdown” configuration of the Hardware pin
1 = Resistor 3 is NOT forced to the hardware pin “shutdown” configuration
0 = Resistor 3 is forced to the hardware pin “shutdown” configuration
R3A: Resistor 3 Terminal A (P3A pin) Connect Control bit
This bit connects/disconnects the Resistor 3 Terminal A to the Resistor 3 Network
1 = P3A pin is connected to the Resistor 3 Network
0 = P3A pin is disconnected from the Resistor 3 Network
R3W: Resistor 3 Wiper (P3W pin) Connect Control bit
This bit connects/disconnects the Resistor 3 Wiper to the Resistor 3 Network
1 = P3W pin is connected to the Resistor 3 Network
0 = P3W pin is disconnected from the Resistor 3 Network
R3B: Resistor 3 Terminal B (P3B pin) Connect Control bit
This bit connects/disconnects the Resistor 3 Terminal B to the Resistor 3 Network
1 = P3B pin is connected to the Resistor 3 Network
0 = P3B pin is disconnected from the Resistor 3 Network
R2HW: Resistor 2 Hardware Configuration Control bit
This bit forces Resistor 2 into the “shutdown” configuration of the Hardware pin
1 = Resistor 2 is NOT forced to the hardware pin “shutdown” configuration
0 = Resistor 2 is forced to the hardware pin “shutdown” configuration
R2A: Resistor 2 Terminal A (P0A pin) Connect Control bit
This bit connects/disconnects the Resistor 2 Terminal A to the Resistor 2 Network
1 = P2A pin is connected to the Resistor 2 Network
0 = P2A pin is disconnected from the Resistor 2 Network
R2W: Resistor 2 Wiper (P0W pin) Connect Control bit
This bit connects/disconnects the Resistor 2 Wiper to the Resistor 2 Network
1 = P2W pin is connected to the Resistor 2 Network
0 = P2W pin is disconnected from the Resistor 2 Network
R2B: Resistor 2 Terminal B (P2B pin) Connect Control bit
This bit connects/disconnects the Resistor 2 Terminal B to the Resistor 2 Network
1 = P2B pin is connected to the Resistor 2 Network
0 = P2B pin is disconnected from the Resistor 2 Network
