SYNC_EVCB

This structure describes a sync pulse event. This event is used by master stream handlers to report synchronization pulses to the Sync/Stream Manager. Each slave stream handler must also register a SYNC_EVCB with the Sync/Stream Manager that will be used by the Sync/Stream Manager to report synchronization pulse to slave streams. This event cannot be enabled with the SpiEnableEvent function call.
