Underrange bits – These bits are set if the input signal is below the input
channel’s minimum range. Bit 00 corresponds to channel 0, bit 01
corresponds to channel 1, and so on.
08…15 (10…17)
Overrange bits – These bits are set if 1), the input signal is above the
input channel’s maximum range, or 2), an open detector is detected. Bit 08
(10) corresponds to channel 0, bit 09 (11) corresponds to channel 1,
and so on.
