Function

7:6 Reserved Read returns zero.

5:4

CLC[1:0] Line Capacitance Compensation.

00 = Off

01 = 4.7 nF

10 = 10 nF

11 = Reserved

3

TISE

Two-Wire Impedance Synthesis Enable.

0 = Two-wire impedance synthesis disabled.

1 = Two-wire impedance synthesis enabled.

2:0

TISS[2:0] Two-Wire Impedance Synthesis Selection.

000 = 600 Ω

001 = 900 Ω

010 = Japan (600 Ω + 1 µF); requires RZREF = 12 kΩ and

C3, C4 = 100 nF

011 = 900 Ω + 2.16 µF; requires RZREF = 18 kΩ and

C3, C4 = 220 nF

100 = CTR21 270 Ω + (750 Ω || 150 nF)

101 = Australia/New Zealand 220 Ω + (820 Ω || 120 nF)

110 = Slovakia/Slovenia/South Africa 220 Ω + (820 Ω || 115 nF)

111 = China 200 Ω + (680 Ω || 100 nF)
