TTX
KAn0, KAn1 = KA coefficient for Ch #n
According to the value of each couple of bits, the KA block is set in the following condition:
KAn1 KAn0
0
X KA block disabled
1
0 KA set for low gain
1
1 KA set for high gain
When the application involves also the metering pulse signal the AFE of the STLC5048 must be adapted in or-
der to manage also this signal. For this purpose is provided the TTX bit.
TTX = 0: the current application is not using the metering pulse signal
TTX = 1: the current application is using the metering pulse signal

To disable this function the T0 bit must be set to 0.
To enable this function the T0 bit must be set to 1; the time-out value is set by means of T<15..1> bits.
Time_out = (T_OUT[15:1]*62.5 + 31.24)ns
The minimum step is 62.5 ns.
