4.4 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 information 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.

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, or configurations that must be the same for all channels

within a group of channels.

3x+0 . . . 7 Over Range Flag: Bit 3

This is a nonfatal over range flag. The bit is set to 1 when an input

value is read within one count of the maximum range value. When

the input value is within normal limits the flag is automatically reset

to 0.
