The variable gain of Current sense feedback ratio for ST/CS channels (ST0/CS0 …

ST7/CS7). It is applied between the ST/CSx input signal current and both, internal

diagnostics and MUX_CS/ST signal current.

CFR 0

the gain of current sense signal to internal current comparator is 1:10 (default)

the gain of current sense signal to internal current comparator is 1:1
