SCR4 Configuration Register 4
Configuration register SCR4 defines the basic SLICOFI settings which enable / disable
the programmable digital filters and the second tone generator.
Reset value: 00

TH
Set transhybrid Balancing Filter – together with the bit FIXC (SCR5-5).
For FIXC = 1 the TH-Filter is set to H
TH
= for Z
BRD
;
for FIXC = 0:
TH = 0
TH-filter is disabled
TH = 1
TH-filter is enabled (use programmed values)
Set DSP-implemented Impedance Matching Filter - together with the bit
FIXC (SCR5-5).
For FIXC = 1 the IM-Filter is set to H
IM
= for 900;
for FIXC = 0:
IM = 0
IM-filter is disabled
IM = 1
IM-filter is enabled (use programmed values)
Enable FRX- (Frequency Response Transmit) Filter
FRX = 0
FRX-filter is disabled (H
FRX
= 1)
FRX = 1
FRX-filter is enabled (use programmed values)
Enable FRR- (Frequency Response Receive) Filter
FRR = 0
FRR-filter is disabled (H
FRR
= 1)
FRR = 1
FRR-filter is enabled (use programmed values)
Set AX- (Amplification/Attenuation Transmit) Filter
AX = 0
AX-filter is set to default value (H
AX
= 10 dB)
AX = 1
AX-filter is enabled (use programmed values)
Set AR- (Amplification/Attenuation Receive) Filter
AR = 0
AR-filter is set to default value (H
AR
=
15.11 dB)
AR = 1
AR-filter is enabled (use programmed values)
Enable programmable Test Tone Generator 2
ETG2 = 0
Test Tone Generator 2 is disabled
ETG2 = 1
Test Tone generator 2 is enabled
User programmable frequency or fixed frequency is selected
PTG = 0
fixed frequency for both Test Tone Generators
TG1 = 1008 Hz, TG2 = 2 kHz
PTG = 1
