AFE coefficient (AFE_CFF)
Reset value = AA00h
Table 76.
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
0
1
1
When the application involves also the metering pulse signal the AFE of the STLC5048
must be adapted in order to manage also this signal. For this purpose is provided the TTX
bit.

Timeout value (T_OUT)
Reset value=FFFFh
Table 77.
Reset value = Maximum value = FFFFh (2048 µs)
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.
