• Timer/Counter I/O Models use a timer/counter circuit in the Neuron Chip or Smart
Transceiver. Each Neuron Chip and each Smart Transceiver has two timer/counter
circuits: One whose input can be multiplexed, and one with a dedicated input.
Timer/counter I/O models include the following types:
Input Model Types Output Model Types
dualslope edgedivide
edgelog frequency
infrared infrared_pattern
ontime oneshot
period pulsecount
pulsecount pulsewidth
quadrature stretchedtriac
totalcount triac
triggeredcount
• Serial I/O Models are used for transferring data serially over a pin or a set of pins.
The neurowire, i2c, magcard, magcard_bitstream, magtrack1, and serial I/O
models are mutually exclusive within a single Neuron Chip or Smart Transceiver.
Both the input and output versions of a serial I/O model can coexist within a single
Neuron Chip or Smart Transceiver. Serial I/O models include the following types:
Serial Input Model Types Serial Output Model Types
bitshift bitshift
magcard serial
magcard_bitstream
magtrack1
serial
wiegand
Serial Input/Output Model Types
i2c
neurowire
sci
spi
• Parallel I/O Models are used for high-speed bidirectional I/O. I/O models within this
group use all of the Neuron Chip or Smart Transceiver I/O pins. The parallel I/O
models include the following types:
Parallel Input/Output Model Types
muxbus
parallel
Table 29 through Table 33 list the available I/O models within each category. Figure 46
summarizes the pin configuration for each of the I/O models. A single device can use various
I/O models of different types simultaneously.
