Table 18. DPS Register 1
Address Default Data Bits, MSB First
0x2 0x0000 Bit Name Function
15
SW-INH
This bit enables the force amplifier when high and disables the amplifier when low. This bit is AND’d with the
HW_INH
hardware inhibit pin.
14 Reserved Reserved, set to 0.
13 I[2:0] Current range addressing. These bits allow selection of the required current range.
12
11
I Action
0 ±5 µA current range.
1 ±25 µA current range.
2
±250 µA current range.
3 ±2.5 mA current range.
4 ±25 mA current range.
5 External Range 2.
6 External Range 1.
7 Reserved.
10 CMP[1:0] Comparator function. CMP1 acts as a comparator output enable, whereas CMP0 selects between a
comparing DUT current or voltage; by default, the comparators are high-Z on power-on.
9
CMP Action
0 Comparator outputs high-Z.
1 Comparator outputs high-Z.
2
Compare DUT current.
3 Compare DUT voltage.
8 ME[3:0] Bits ME[3:0] allow selection of the required measure mode, allowing the MEASOUT line to be disabled;
connect to the temperature sensor or enable it for measurement. ME3 is MEASOUT enable/disable; when
high, MEASOUT is enabled, and ME[2:0] can be used to preselect the measuring parameter. Where a
number of MEASOUT lines are connected together and passed to a common ADC, this function can allow
for much faster measurement time between channels because the slew time of the measurement buffer is
reduced. For details on diagnostic functions, see Address 0x7, the diagnostic register.

1 Connect MEASOUT to I
SENSE.
2 Connect MEASOUT to V
SENSE.
3 Connect MEASOUT to K
SENSE.
4
Connect MEASOUT to
TSENSE.
5 Connect MEASOUT to DUTGND SENSE.
6 Connect MEASOUT to diagnostic functions: DIAG A (see Address 0x7).
7 Connect MEASOUT to diagnostic functions: DIAG B (see Address 0x7).
4 CLEN Clamp enable; set high to enable the clamp; set low to disable the clamp. This bit is OR’d with the
hardware CLEN pin.
3:0 Unused Set to 0.
