MFR_VIN_MIN : Returns minimum input voltage as two data
bytes of information in Linear format (upper five bits are
exponent – fixed at -2, and lower 11 bits are mantissa in
two’s complement format – fixed at 12)
MFR_VOUT_MIN : Returns minimum output voltage as two
data bytes of information in Linear format (upper five bits
are exponent – fixed at -10, and lower 11 bits are mantissa
in two’s complement format – fixed at 614)
MFR_SPECIFIC_00 : Returns information related to the type
of module and revision number. Bits [7:2] in the Low Byte
indicate the module type (xxxxxx corresponds to the
UDXS1212 series of module), while bits [7:3] indicate the
revision number of the module.
