S ON T HE SMBUS
T he details of using the SMBus are described later, but
the register names associated with the Supply Fault Detec-
tor blocks, the bitmap of those registers, and the function
of each of the bits is described in the following tables.
T he tables show how to set up UV threshold, UV hyster-
esis, OV threshold, OV hysteresis, glitch filtering and
fault type for each of the SFD
’
s on the ADM1060.
