CP chip
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. 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.
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 must be connected to Vcc.
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 Vcc.
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.
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 MC2542, all 4 pins are valid. For MC2522, only PosLim1 and PosLim2 are
valid. For MC2512, 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 Vcc must be via a series resistor.
Invalid axis pins may also be left unconnected or connected to GND.
