* TODO: Add smarter short detection? Automatically run an electrical test at
|
|
|
|
* startup and leave everything in input mode if shorts are detected?
|
|
|
|
* I'm especially thinking about the case of SIMM control pins shorted
|
|
|
|
* together, like CS and OE, which will default to opposite output values.
|
|
|
|
* Is this even worth implementing? It's probably only useful when testing
|
|
|
|
* newly-built SIMMs. We would need to implement a protocol for this so
|
|
|
|
* the programmer software can be alerted that a short was detected.
