SMD1108
Preliminary
Registers 90 through 93 control the sources of activation
for the HEALTHY# and FAULT# outputs. For the
HEALTHY# output to be true all the selected sources must
be within their limits. This is effectively an ANDing
function. For the FAULT# output to be true only one of the
selected sources need be out of limits (ORing). If the
same sources for HEALTHY# and FAULT# are selected
then only one of the two outputs can be true at one time.
