This function should generally be left in the default mode. The alternate mode applies to a different model of the module.

Parameters

is the VXI instrument session pointer returned by the age1439_init function.

AGE1439_PRESCALE_BY_1 divides the reference clock by one.

AGE1439_PRESCALE_BY_4 divides the reference clock by four.

Returns a pointer to the current value of refPrescalerPtr.

Return Value

AGE1439_SUCCESS indicates that a function was successful.

Values other than AGE1439_SUCCESS indicate an error condition or other important status condition. To determine the error message, pass the return value to “age1439_error_message” on page 102.
