SCR3 Configuration Register 3
Configuration register SCR3 defines the meterpulse settings and the Data Upstream
Persistency Counter.
Reset value: 8A
H
TTXNO
Meterpulses are represented by teletax (TTX) with 12 or 16 kHz or with
Reverse Polarity
TTXNO = 0
Meterpulses are represented with 12 kHz or 16 kHz
TTXNO = 1
Meterpulses are represented with Reverse Polarity
Teletax-signal with 12 kHz or 16 kHz
TTX12 = 0
16 kHz teletax-signal
TTX12 = 1
12 kHz teletax-signal
The reversal pulse is either soft or hard
SOREV = 0
hard reversal
SOREV = 1
soft reversal
Note: For proper function special coefficients generated by SLICOS should be used.
TTX12
SOREV
To realize this function following settings must be done:
1. Enable the testregisters (Configuration Register 5: SCR5-1 (ENTR)=1), (
page 32
)
2. The testregisterblock must be load with STCR3-0 (SOFTVER) = 1, (see
chapter
10.3
)
