address, destination address, and priority attribute vector into an existing
receive transaction and the message’s transaction number matches the entry’s
transaction number.
Receive transaction entries are freed after the receive timer expires. The receive
timer duration is determined by the destination device and varies as a function of
the message addressing mode. For group addressed messages, the receive timer
is determined by the address table. For Neuron ID addressed messages, the
receive timer is fixed at eight seconds. For other addressing modes, the non-
group receive timer in the configuration data structure is used.
