Hi Ralph,

Justa small tip since you mentioned that you are entering this field of coding for MCUs.

Adapt a specific style of coding. The way you have typed it is defenitley a strain to read - in all caps. And one doesnt know where the code ends and comments begin. In fact I have made the same mistakes when I started.

One style that is easy on the eyes is :

Labels start with a capital and are in sentence case.

Instructions are all in lower case except for SFRs which are in caps.

Comments are in sentence case.

Just a suggestion.
