CFG2 register (isolated side)

The CFG2 register has the structure of Table 31.

The SENSEth bits set the SENSE comparator threshold according to Table 32. Refer to

Section 7.8 on page 33

for details.

The DESATcurr parameter sets the current sourced by the DESAT pin according to Table 33

and the DESATth parameter sets the DESAT comparator threshold according to Table 34.

Refer to Section 7.6 on page 30 for details.
