How to use the nidmm.attributes.AttributeEnum function in nidmm

Changing the function or the range through this attribute or through niDMM_ConfigureMeasurementDigits  resets the value of this attribute to the default value.
    '''
    cache = attributes.AttributeViBoolean(1050004)
    '''
    Specifies whether to cache the value of attributes. When caching is enabled,  the instrument driver keeps track of the current instrument settings and  avoids sending redundant commands to the instrument. Thus, it significantly  increases execution speed. The instrument driver can choose always to cache  or to never cache particular attributes regardless of the setting of this  attribute. The default value is VI_TRUE (1). Use the niDMM_InitWithOptions  function to override this value.
    '''
