 * NOTE: 1) An individual callback is to be registered for each Slave and Master

 * stamp interrupts either the same callback or two separate callbacks the API has
 * to be invoked twice.
 *       2) On the IXDP465 Development Platform, the Auxiliary Timestamp signal for 
 * slave mode is tied to GPIO 8 pin. This signal is software routed by default to 
 * PCI for backwards compatibility with the IXDP425 Development Platform. This
 * routing must be disabled for the auxiliary slave time stamp register to work 
 * properly. The following commands may be used to accomplish this. However, refer
 * to the IXDP465 Development Platform Users Guide or the BSP/LSP documentation for
 * more specific information.
