This register provides the Packet Descriptor Reference Small Buffer Free Queue
write address.
Notes
1. This register is not byte addressable. Writing to this register modifies all the
bits in the register. Byte selection using byte enable signals (CBEB[3:0]) are
not implemented. However, when all four byte enables are negated, no
access is made to this register.
