Hi
I suggest to Sunny to have the video on full screen and have the mouse pointer over some part of the area or hit the space bar and stop the video and start it.
I just started and stopped the tutorial when i wanted to see the detail because Chobu's fingers can go a little fast when you are taking in the information.
It took me about 5 minutes to see what was going on.
When you have numbers and things like CONTROL ,MSB,LSB etc we tend to look too deep and then the tech terms can confuse you.
Just keep going over the area that is confusing to you and it will come all of a sudden.
Big Top Hats off for Chokbu as his video's are excellent
All the Best
John
