DEFLAGS on Cortex A9 FPU

The Cortex A9 FPU Technical Reference Manual describe the FPSCR register and says:

The exception flags, bit [7] and bits [4:0] of the FPSCR are exported on the DEFLAGS output so they can be monitored externally to the processor, if required.

The question is very simple: Where is DEFLAGS, How can I access this register? 

My aim is to monitor the exception bits and throw an interrupt when an exception is detected.

Many thanks to all.
