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. Bits [7:2] in the Low Byte indicate the module type
(000100 corresponds to the MDT040 series of module). Bits
1:0 in the High Byte are used to indicate the manufacturer ID,
with 00 reserved for GE.
