output
Multi-purpose Address lines. These pins comprise the CP chip’s external address
bus, used to select devices for communication over the data bus.
Addr0
,
Addr1
,
and
Addr15
are connected to the corresponding
CPAddr
pins on the I/O chip,
and are used to communicate between the CP and I/O chips.
Other address pins may be used for DAC output, parallel word input, or user-
defined I/O operations. See the
Navigator Motion Processor User’s Guide
for a
complete memory map.
input
This is the CP chip clock signal. It should be connected to I/O chip pin 24,
CPClk
.
CP chip analog power supply voltage. This pin must be connected to the analog
input supply voltage, which must be in the range 4.5-5.5 V
If the analog input circuitry is not used, this pin may be left unconnected.
CP chip analog high voltage reference for A/D input. The allowed range is
AnalogRefLow
to
AnalogVcc
.
If the analog input circuitry is not used, this pin may be left unconnected.
CP chip analog low voltage reference for A/D input. The allowed range is
AnalogGND
to
AnalogRefHigh
.
If the analog input circuitry is not used, this pin may be left unconnected.
CP chip analog input ground. This pin must be connected to the analog input
power supply return.
If the analog input circuitry is not used, this pin may be left unconnected.
These signals provide general-purpose analog voltage levels which are sampled
by an internal A/D converter. The A/D resolution is 10 bits.
The allowed range is
AnalogRefLow
to
AnalogRefHigh
.

input
input
These signals provide inputs from the positive-side (forward) travel limit
switches. On power-up or
Reset
these signals default to active
low
interpretation,
but the interpretation can be set explicitly using the
SetSignalSense
instruction.
For MC2340 all 4 pins are valid. For MC2320 only
PosLim1
and
PosLim2
are
valid. For MC2310 only
PosLim1
is valid.
WARNING! If a valid axis pin is not used, its signal must be tied
high. PosLim2 is an output during device reset and as such any
connection to GND or V
cc
must be via a series resistor.
Invalid axis pins may also be left unconnected.
