KD Filter (KDF)

The register is used to set the 3 coefficients (each of 16 bits) of the KD filter of the channel #n.

AFE Coefficient (AFE_CFF)

Reset value = AA00h

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

KA block disabled

KA set for low gain

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

Timeout value (T_OUT)

Reset Value=FFFFh

Reset value = Maximum value = FFFFh (2048 us)

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.
