Assembly Loop: How many times does NOP run?
Reply to thread
Message
[QUOTE="rcgldr, post: 4336845, member: 17595"] You could run the loop and read the timer before and after the loop. However the timer may wrap around if your loop takes too long. One way to avoid this would be to intercept the timer interrupt and use an interrupt count as the "upper" bits of the counter timer. Depending on how the timer is programmed, it may count down by 1 or count down by 2 (if it's by 2, there's a sequence of port I/O writes and reads to get the upper bit of the counter). [/QUOTE]
