ICON (EXCITATION CURRENT SOURCES CONTROL REGISTER)
The ICON register is used to configure the current sources and the burnout detection source.

Note that a write to the ICON register has an immediate effect but does not reset the ADCs. Therefore, if a current source is changed while
an ADC is already converting, the user must wait until the third or fourth output at least (depending on the status of the chop mode) to
see a fully settled new output.

Description
Not Implemented. Write Don’t Care.
Burnout Current Enable Bit.
When set, this bit enables the sensor burnout current sources on primary ADC channels AIN4/AIN5 or
AIN6/AIN7. Not available on any other ADC input pins or on the auxiliary ADC (ADuC845 only).
Not Implemented. Write Don’t Care.
Not Implemented. Write Don’t Care.
IEXC2 Pin Select (0 = AIN 8/AIN1 = AIN7).
IEXC1 Pin Select (0 = AIN7/AIN1 = AIN 8).
IEXC2 Enable Bit (0 = disable).
IEXC1 Enable Bit (0 = disable).
