Description
These signals provide inputs from the negative-side (reverse) 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 NegLim1 and NegLim2 are
valid. For MC2512, only NegLim1 is valid.

WARNING! If a valid axis pin is not used, its signal must be tied
high. NegLim1 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.
94
Output
Each of these pins can be conditioned to track the state of any bit in the Status
95
registers associated with its axis.
96
For MC2542, all 4 pins are valid. For MC2522, only AxisOut1 and AxisOut2 are
97
valid. For MC2512, only AxisOut1 is valid.
Invalid or unused pins may be left unconnected.

These are general-purpose programmable inputs. They may be used as a
breakpoint input, to stop a motion axis, or to cause an UPDATE to occur.
For MC2542, all 4 pins are valid. For MC2522, only AxisIn1 and AxisIn2 are valid.
For MC2512, only AxisIn1 is valid.
Invalid or unused pins may be left unconnected or connected to GND.
2, 7, 13, 21, 35, 36, 40, CP digital supply voltage. All of these pins must be connected to the supply
47, 50, 52, 60, 62, 93, voltage. Vcc must be in the range 4.75 - 5.25 V

WARNING! Pin 35 must be tied HIGH with a pull-up resistor. A
nominal value of 22K Ohms is suggested.

These signals must be tied to AnalogGND.
If the analog input circuitry is not used, these pins must be tied to GND.
45, 48, 68, 69, 70, 73, These signals may be connected to GND for better noise immunity and reduced
90, 91, 101, 102, 105, power consumption or they can be left unconnected (floating).
