MOTOROLA LONWORKS TECHNOLOGY
MC143120E2
2–6
Neuron Chip Distributed
Communications and Control
Processor
The MC143120E2 contains the LonTalk protocol in 10K ROM. It differs from
the MC143120B1 in that it contains 21 I/O models. Bit Shift, Serial Input, and
Serial Output I/O models are not in the ROM rmware, but can be loaded into
EEPROM by the LonBuilder tool if needed. In addition, 21 I/O models are
integrated with ROM to provide simplied sense and control device interfacing.
