in the middle of the bit time. The signal idles at the normal quiescent supply current. A logic low is defined as an increase in
current at the middle of a bit time. A logic high is defined as a decrease in current at the middle of a bit time. There is always a
transition in the middle of the bit time. If consecutive “1” or “0” data are transmitted, There will also be a transition at the start of
a bit time.
