Remote sensor interface

WSI remote sensor data/fault register

RS_DATA_RSDR_x register stores status bits of WSS interface. Output format depends on

the status of bit 15.

No Fault condition:

Bit 9:8

FIRST_RANGE_SEL (valid only for

adaptive thresholds):

00 ==> ∆Ith1MIN=6.25mA,

∆Ith1MAX=7.75mA;

01 ==> ∆Ith1MIN=5.5mA,

∆Ith1MAX=8.5mA;

10 ==> ∆Ith1MIN=4.75mA,

∆Ith1MAX=9.25mA;

11 ==> ∆Ith1MIN=4.0mA,

∆Ith1MAX=10.0mA;

Bit 7:0

WSI_FIRST_TH[7:0]:

In case of fixed thresholds this is

used to calculate low threshold

(see formula in 4.1).

In case of adaptive thresholds this

is the minimum value of IB0

(IB0MIN range from 0 to 24 mA).

In both cases LSB=93.75 µA typ.
