The GADDRn registers are written by the user. Together these registers represent, depending on
RCTRL[GHTX], either the 256 entries of the group address hash table, or the last 256 entries of the
extended group address hash table used in the address recognition process. The user can enable a hash
entry by setting the appropriate bit. A hash table hit occurs if the DA CRC result points to an enabled hash
entry.

Group Address Registers 0–7 (GADDR n )
IGADDR0 contains entries 0–31 of the 256-entry individual hash table and IGADDR7 represents entries
224–255. When RCTRL[GHTX] = 1, IGADDR0 contains entries 0–31 of the 512-entry extended group hash
table and IGADDR7 represents entries 224–255.
GADDR0 contains entries 0–31 of the 256-entry group hash table and GADDR7 represents entries
224–255. When RCTRL[GHTX] = 1, GADDR0 contains entries 256–287 of the 512-entry extended group
hash table and GADDR7 represents entries 480–511.
