MFR_FAULTB00_PROPAGATE, MFR_FAULTB01_
PROPAGATE, MFR_FAULTB10_PROPAGATE and
MFR_FAULTB11_PROPAGATE
These manufacturer specific commands enable channels
that have faulted off to propagate that state to the ap-
propriate fault pin. There are two zones in the LTC2978.
In zone 0, faulted off states for channels 0 through 3 can
be propagated to FAULT00 or FAULT01. In zone 1, faulted
off states for channels 4 through 7 can be propagated to
FAULT10 or FAULT11. See Figure 13.
