O_ENABLE_LINE_CHECK:

This operate call allows the user to enable open-

loop checking on the current version of the SM-

ADC1. The syntax is as follows:

<analog var> := OPERATE(<iovar>, O_ENABLE_LINE_CHECK,

<var>);

where <analog var> represents the analog return variable and can

be zero if the operate call is supported and the

correct <iovar> is passed or non-zero if an

error occurred.

<iovar> is the variable name for the channel where the

operate call is to take effect.

<var> is not used.

O_DISABLE_LINE_CHECK:

This operate call allows the user to disable open-

loop checking on the current version of the SM-

ADC1. The syntax is as follows:

<analog var> := OPERATE(<iovar>, O_DISABLE_LINE_CHECK,

<var>);

where <analog var> represents the analog return variable and can

be zero if the operate call is supported and the

correct <iovar> is passed or non-zero if an

error occurred.

<iovar> is the variable name for the channel where the

operate call is to take effect.
