Description
Multi-purpose Address lines. These pins comprise the CP chip’s external address
bus, used to select devices for communication over the data bus.
They may be used for DAC output, parallel word input, or user-defined I/O
operations. See the
Pilot Motion Processor User’s Guide
for a complete memory map.

output
input
This is the clock signal for the motion processor. It is driven at a nominal 20
MHz.
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 must be connected to V
cc
.
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 must be connected to V
cc
.
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 must be connected to GND.
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 must be connected to GND.
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
.
Any unused pins should be tied to AnalogGND.
If the analog input circuitry is not used, these pins should be tied to GND.

input
output
This pin provides the Pulse Width Modulated signal to the motor. This is the
magnitude signal.
The PWM resolution is 10 bits at a frequency of 20.0 KHz.
This pin provides the sign (direction) of the PWM signal to the motor amplifier.
This signal is
high
when the PWM output is positive, and
low
when it is negative.
These pins provide the A and B quadrature signals for the incremental encoder.
When the axis is moving in the positive (forward) direction, signal A leads signal
B by 90°.
The theoretical maximum encoder pulse rate is 5.1 MHz. Actual maximum rate
will vary, depending on signal noise.
NOTE
: Many encoders require a pull-up resistor on each signal to establish a
proper high signal. Check your encoder’s electrical specification.
