ADSP-21371 - Can clock at CLKIN be verified using boundary scan?

The BSDL file for this device does not show a cell type and characteristics for the CLKIN (pin 83). Is there a mistake in the BSDL file or is there truly no boundary scan cell on pin 83? My customer wants me to verify presence of an external clock at this pin using boundary scan. The source is a free-running clock oscillator which feeds pin 83 via a non-boundary-scan clock buffer.
