The buffer configuration may be modified from the host by sending Write Memory
network management messages, specifying the appropriate fields of the Read-only
Data Structure. The application checksum must be updated. For more details on
network management messages, and the Neuron Chip data structures, see the
Neuron Chip Data Book
