This memory is used internally by the TSIU. Before a port is enabled, the state field of
groups to be enabled must be set to zero before the port is enabled. The relevant group
register is found at an offset of the group number from the base address. This is typically
done on reset of the chip, or immediately after a port is disabled. There is one register per
group.
