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.
