I/O Model Reference 3
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 1 on page 4 through Table 5 on page 6 list the available I/O models within
each category.
Figure 1 on page 9 summarizes the pin configuration for each of
the I/O models. A single device can use various I/O models of different types
simultaneously.
