Functional Description

Figure 192 Postprocessing Channel Block Diagram for Voltage and Temperature Measurements

As shown in

an adjustable filter can be applied for the upper and the lower measurement channel,

which averages 2, 4, 8 or 16 measurement values continuously. The filtered signal or the demultiplexed ADC
output signal ADC_OUTX is compared with an upper threshold TH_UP_CHX and a lower threshold
TH_LO_CHX. When the thresholds are exceeded, the comparator outputs get active. For all measurement
modes a freely adjustable hysteresis can be defined which is defined with the HYST_UP_CHX and
HYST_LO_CHX values.
In addition to the first filter stage, the second filters (counters) integrate the comparator output values
S

TH_UP/LO_CHX

until an individual upper and lower timing threshold 2

CNT_UP/LO_CHX

is reached. When reaching the

upper timing threshold 2

CNT_UP_CHX

, the upper counter increment is stalled and the status output CHX_UP_STS

is set. For MMODE_OV = 1, the inverted lower comparator output signal S

TH_LO_CHX

is normalized again. When

the output signal is above TH_LO_CHX, the lower counter is incremented until the max. threshold 2

CNT_LO_CHX

is reached. Individual interrupts for the upper and lower channel can be triggered with the rising edge of the
status signals UP/LO_X_STS.
In general the IIR filter stage suppresses higher frequency noise efficiently and triggering with the upper and
lower threshold TH_UP/LO_CHX are dependent on the measured values. Hence short high-level spikes might
pass the thresholds. In opposite to the first stage the nature of the second filter stage is more a time filter,
which is less dependent on the measurement values but on event durations of S

TH_LO/UP_CHX

as generated by

the first comparator stage. Therefore the second stage has a lower noise suppression performance for higher
frequencies and also adds a delay for the trigger time proportional to 2
