Hi
I'm using MCU 8051. Please have a look on the video and please help me with the queries below (you can also queries embedded in the video): http://www.youtube.com/watch?v=RKn9tEpM5XE
Q1: There is some problem with the code because see the value "A" has taken on. The value for R0 is also wrong.
Q2: The value of PC goes up by 2 for every line. I have read that this instruction MOV A, 80H occupy two bytes instead of one and that's the reason PC goes up by '2' for every line of the code. But can't that instruction be saved on a single byte so that the PC goes up by only '1' byte?
Regards
PG

Rich (BB code):
ORG 0H
MOV A, 80H
MOV R0, 81H
ORG 80H
DB 10
DB 12
END
