QIf a second /CONVST pulse occurs before the end of conversion point, EOC, what
will happen. Will the first request be cancelled and a new conversion begun?
AOnce a conversion is started by pulling the /CONVST pin low if the /CONVST pin
is brought low again before the EOC point the second request is ignored and the
result of the first request will be available as normal once the original
conversion time has elapsed.
