4.3 Channel Status (Registers 3x+ 0 through 3x+7)
As described in Section 2.5, register 4x bits 1and 2 can be set to allow
monitoring of individual channel status (set to “0” and “1” respectively).
You will then be displaying eight channels of status information. As
described below, bits 1-4 provide four different pieces of error informa-
tion specific to that input channel. Bits 5-11 merely confirm what setup
has been created for that feature in configuration register 4x. Bits 12-16
will indicate what channel’s status is being displayed.

Configuration error
Calibration error
3x+0 . . . 7 Calibration Error Flag: Bit 1
The calibration error flag is a fatal error. When the flag is set to “1” the
ADC cannot calibrate within specifications.
3x+0 . . . 7 Configuration Error Flag: Bit 2
The calibration error flag is a fatal error. When the flag is set to “1”
there is a configuration mismatch. Configuration errors include any illegal
configuration, such the selection of an unsupported format or filter option,
