Important: This register is read-sensitive. See the register description for details.

This register returns the contents of the NBRFIFO or 0 if the NBRFIFO is empty. Each read returns
the data that is at the top of the NBRFIFO, and then empties that value from the NBRFIFO. The
alias registers can be used with the LDMIA instruction for more efficient operation (for up to 8
registers). See Cortex™-M3/M4 Instruction Set Technical User's Manual (literature number

SPMU159

)

for more information on the LDMIA instruction.
