setups can be supplied by age1439_clock_setup.
Description
This function selects a front panel clock source that is used to drive the analog to digital converter
(ADC) for single module operation or when a module is used as the master ADC clock source for
a multi-module system.
Parameters

AGE1439_SMB_CLOCK specifies clock input from the front panel Intermodule Clock/SMB
connectors.
AGE1439_BNC_CLOCK specifies clock input from the front panel Ext Clock/Ref BNC
connector.
fpClockPtr returns a pointer to the current value of fpClock.
