MC3110 Technical Specifications
28
Pin Name and number Direction
~Index1
69
Description
This pin provides the Index signal for the incremental encoder. A valid index
pulse is recognized by the processor when
this signal transitions from
high
to
low
.
input
There is no internal gating of the index signal with the encoder A
and B inputs. This must be performed externally if desired. Refer
to the section 7.11 for an example schematic.
~Home1
70
input
This pin provides the Home signal, general-purpose inputs to the position-
capture mechanism. A valid Home signal is recognized by the processor when
~Home
goes
low
.
WARNING! If this pin is not used, its signal should be tied high.
PosLim1
63
input
This signal provides input from the positive-side (forward) travel limit switch.
On power-up or
Reset
this signal defaults to active
low
interpretation, but the
interpretation can be set explicitly using the
SetSignalSense
instruction.
WARNING! If this pin is not used, its signal should be tied high.
NegLim1
64
input
This signal provides input from the negative-side (reverse) travel limit switch. On
power-up or
Reset
this signal defaults to active
low
interpretation, but the
interpretation can be set explicitly using the
SetSignalSense
instruction.
WARNING! If this pin is not used, its signal should be tied high.
This signal is an output during device reset and as such any
connection to GND or V
cc
must be via a series resistor.
AxisOut1
94
output
This pin can be programmed to track the state of any bit in the Status registers.
If this pin is not used it may be left unconnected.
This is a general-purpose or programmable input. It can be used as a breakpoint
input, to stop a motion axis, or to cause an
Update
to occur.
If this pin is not used it may be left unconnected.
On the MC3110 this pin is not used.
On the MC3113, this pin is the synchronization signal. In the disabled mode,
the pin is configured as an input and is not used. In the master mode, the pin
outputs a synchronization pulse that can be used by slave nodes or other devices
to synchronize with the internal chip cycle of the master node. In the slave
mode, the pin is configured as an input and a pulse on the pin synchronizes the
internal chip cycle.
CP digital supply voltage. All of these pins must be connected to the supply
voltage. V
cc
must be in the range 4.75 - 5.25 V

2, 7, 13, 21, 35, 36, 40,
47, 50, 52, 60, 62, 66,
93, 103, 121
WARNING! Pin 35 must be tied HIGH with a pull-up resistor. A
nominal value of 22K Ohms is suggested.
GND
3, 8, 14, 20, 29, 37, 46,
56, 59, 61, 71, 92, 104,
113, 120
78-81
CP ground. All of these pins must be connected to the power supply return.
AGND
These signals must be tied to AnalogGND.
If the analog input circuitry is not used, these pins must be tied to GND.
These signals may be connected to GND for better noise immunity and reduced
power consumption or they can be left unconnected (floating).
unassigned

131
unassigned
These signals must be left unconnected (floating).
