bits 7–5
These bits are set to 0.
bit 4
L0_SW: Selectable switch (see the Block Diagram) that allows for an external shunt resistor to be connected to the
L0 pin.
0 = Switch L0_SW is open (default).
1 = Switch L0_SW is closed.
bit 3
BSC: A control bit that, when OR’d with the state of the BK_SEL pin, selects which bank of registers will be used to
determine the setting of Resistors 0, 1, and 2.
0 = BK_SEL pin determines which bank settings are used.
1 = Bank 1 settings are used.
bit 2
HiZ2: A control bit used to select a high-impedance state for Resistor 2.
If the DIS pin is high, all resistors are high impedance regardless of Hi-Z control pin state. If the DIS pin is low, then
the following is true:
0 = Resistor 2 is not in a high-impedance state (default).
1 = Resistor 2 is placed in a high-impedance state.
bit 1
HiZ1: A control bit used to select a high-impedance state for Resistor 1.
If the DIS pin is high, all resistors are high impedance regardless of Hi-Z control pin state. If the DIS pin is low, then
the following is true:
0 = Resistor 1 is not in a high-impedance state (default).
1 = Resistor 1 is placed in a high-impedance state.
bit 0
HiZ0: A control bit used to select a high-impedance state for Resistor 0.
If the DIS pin is high, all resistors are high impedance regardless of Hi-Z control pin state. If the DIS pin is low, then
the following is true:
0 = Resistor 0 is not in a high-impedance state. (Default)
1 = Resistor 0 is placed in a high-impedance state.
