RENESAS 14305R-2000

The Neuron 5000 Processor includes 3 independent 8-bit logical processors to manage the physical MAC layer, the network, and the user application. These are called the Media-Access Control (MAC) processor, the network (NET) processor, and the application (APP) processor, respectively. At higher system clock rates, there is also a fourth processor to handle interrupts.
