O_SET_LINE_LIMIT:

This operate call allows the user to set the open loop detect level on the current version of the SM-ADC1. The syntax is as follows:

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

where <analog var>

<iovar>

<var>

<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.

is the variable name for the channel where the operate call is to take effect.

is the current value in mA and calculated using the following formula:

var = 0xFFF0 mA 0x14

O_GET_LINE_STATE:

This operate call allows the user to check the line state on the current version of the SM-ADC1. The syntax is as follows:

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

where <analog var>

<iovar>

<var>

<var>);

represents the analog return variable and is zero if an open loop is detected. Otherwise it returns 1.

is the variable name for the channel where the operate call is to take effect.

is not used.
