RE: [CAD_CAM_EDM_DRO] troubleshooting help

Bob:

Standard logic means that a logic level zero is also represented by a
voltage level which is close to zero (normally under 0.8 volts) A logic
level 1 is represented by a voltage level which is close to the power supply
voltage (usually within a volt for 5 volt logic). Inverted logic means that
a logic level zero is represented by the voltage level which is close to the
power supply voltage and a logic level one is represented by a voltage level
close to zero.

|Please explain ' inverted pins '.
|
|Does this mean the pins are normally at 0 volts and goes to -5 volts with
|input?
|Or are the pins at +5 volts normally and go to 0 volts with input?
|
|An uninverted pin would normally be at 0 volts and go to +5 volts with
|input, right?
|
|Thanks,
|

|>Notice that several pins are inverted, per the CMD_MASK.
