I've been trying to determine when a DJNZ loop is halted. For example, does the DJNZ loop subtract one and then check its value, or does it check the value, and if its not zero, subtract one and loop.

If this was the program :

MOV R5, #1
MOV A, #1

Internal_Loop:
ADD A, #1
DJNZ R5, Internal_Loop

End

Basically what I'm asking is "At the end of this program loop, would A be 2 or 3?"
