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.
