Echelon Neuron - Manual (Page 166)

RESOURCE (Resource Control)
The RESOURCE directive is used by the Neuron C compiler to specify various
preferences and requirements to its companion tools (the Neuron Assembler, the
Neuron Linker, and the Neuron Exporter). For example, the compiler specifies
the number of address table entries, aliases, message tags, and other resources
for a device.
Do not specify the RESOURCE directive in your Neuron assembly source.
