Bit 31 represents bundle 63 and bit 0 represents bundle
32. When a bit is set it indicates the corresponding bundle
had a change in one of the bundle’s control word fields: L,
R, M or FRG. The
CW_bits_change_mask register
specifies which of the four Control Word fields can cause
an interrupt when changed. The current state of the four
fields can be read from the Packet Classifier Status
register in the per-bundle status tables (section 11.4.4.1).
