Channel Configuration, Data, and Status 4-15
Over-Range Error (Bit 14)
This bit is set (1) whenever a configured channel detects an over
range condition for the channel data. An over-range condition exists
when the input value is equal to or above the specified upper limit of
the particular sensor connected to that channel.
Channel Error (Bit 15)
This bit is set (1) whenever a configured channel detects an error in
the configuration word, or an error has occurred while acquiring the
A/D data value. If during the auto-calibration process, the module
detects an out-of-range condition for the filter frequency selected for
the channel, the channel error bit is set. An out-of-range condition
occurring during auto-calibration would be the result of an overly
noisy environment, whereby the module cannot maintain accuracy
specifications, thus flagging an error. The error bit is cleared when the
error condition is resolved. The channel data word is not updated
during a period of auto-calibration filter frequency tolerance errors.
