I Operations of Sample Programs
Figure Bb shows the sample program listings.
The behaviors of samples 1 and 2 are slightly different. This is because, while the serial driver in
sample 1 is implemented based on interruption, the one in sample 2 is implemented based on
polling. The remainder of this appendix applies mainly to sample 1 whose operation is more
difficult to understand than sample 2.
