Note 1:
R-1
D8
2:
The hardware SHDN pin (when active) overrides the state of these bits. When the SHDN pin returns to the
inactive state, the TCON register will control the state of the terminals. The SHDN pin does not modify the
state of the TCON bits.
These bits do not affect the wiper register values.
D8: Reserved. Forced to “1”
R1HW: Resistor 1 Hardware Configuration Control bit
This bit forces Resistor 1 into the “shutdown” configuration of the Hardware pin
1 = Resistor 1 is NOT forced to the hardware pin “shutdown” configuration
0 = Resistor 1 is forced to the hardware pin “shutdown” configuration
R1A: Resistor 1 Terminal A (P1A pin) Connect Control bit
This bit connects/disconnects the Resistor 1 Terminal A to the Resistor 1 Network
1 = P1A pin is connected to the Resistor 1 Network
0 = P1A pin is disconnected from the Resistor 1 Network
R1W: Resistor 1 Wiper (P1W pin) Connect Control bit
This bit connects/disconnects the Resistor 1 Wiper to the Resistor 1 Network
1 = P1W pin is connected to the Resistor 1 Network
0 = P1W pin is disconnected from the Resistor 1 Network
R1B: Resistor 1 Terminal B (P1B pin) Connect Control bit
This bit connects/disconnects the Resistor 1 Terminal B to the Resistor 1 Network
1 = P1B pin is connected to the Resistor 1 Network
0 = P1B pin is disconnected from the Resistor 1 Network
R0HW: Resistor 0 Hardware Configuration Control bit
This bit forces Resistor 0 into the “shutdown” configuration of the Hardware pin
1 = Resistor 0 is NOT forced to the hardware pin “shutdown” configuration
0 = Resistor 0 is forced to the hardware pin “shutdown” configuration
R0A: Resistor 0 Terminal A (P0A pin) Connect Control bit
This bit connects/disconnects the Resistor 0 Terminal A to the Resistor 0 Network
1 = P0A pin is connected to the Resistor 0 Network
0 = P0A pin is disconnected from the Resistor 0 Network
R0W: Resistor 0 Wiper (P0W pin) Connect Control bit
This bit connects/disconnects the Resistor 0 Wiper to the Resistor 0 Network
1 = P0W pin is connected to the Resistor 0 Network
0 = P0W pin is disconnected from the Resistor 0 Network
R0B: Resistor 0 Terminal B (P0B pin) Connect Control bit
This bit connects/disconnects the Resistor 0 Terminal B to the Resistor 0 Network
1 = P0B pin is connected to the Resistor 0 Network
0 = P0B pin is disconnected from the Resistor 0 Network
