error_code SMADCEnableConversion(u_int8 PortNr, u_int8
Description
This function checks if an SM-PT100 board is fitted on the specified port and
if the channel is valid and forces the HW task to convert the raw values. If
the flag enable is TRUE (<>0), then conversion of raw values to degrees
Celsius is executed, else if (enable=FALSE) no conversion takes place. The
function invalidates converted data, if enable is set to FALSE.
