3.6.1 Input Assembly Status Bit Definitions

Under Range and Over Range trip points are determined by the Low Range and
High Range values in the Table 3-3. Data Formats.
The CF bit is set when any of the other status bits are set.
CF = Channel Fault status; 0 = no error, 1 = fault
UR = Underrange; 0 = no error, 1 = fault
OR = Overrange; 0 = no error, 1 = fault
OC = Open Circuit: 0 = no error, 1 = fault (not valid for all ranges)
n/a = Always 0.
