Switches
Some 1-wire devices have the ability to turn on/off a digital line.
- The line is usually on-off conducting to ground
- The current sink is limited
- Voltage range is specified
- The line is usually "tri-state"
- Actual logical state can be tested
- Actual state really only makes sense in "non-conducting" (off) state
- The usual properties associated are:
- sensed -- the actual logical state of the line (makes most sense in "non-conducting"
- 0 -- GND voltage
- 1 -- 5V (or so)
- PIO -- the conducting setting
- 0 -- off so non-conducting (to ground)
- 1 -- on, so conducting to ground.
- Latch -- the state "set"
- 0 off intended
- 1 on intended
