Design Tips
Question 1:
Answer 1:
If you are polling TMR0 to see if it has rolled over to zero. You could do this by executing:
wait
Two possible scenarios to lose clock cycles are:
1.
2.
If you are incrementing TMR0 from the internal instruction clock, or an external source that
is about as fast, the overflow could occur during the two cycle GOTO, so you could miss it.
In this case the TMR0 source should be prescaled.
Or you could do a test to see if it has rolled over by checking for less than a nominal value:
When writing to TMR0, two instruction clock cycles are lost. Often you have a specific time
period you want to count, say 100 decimal. In that case you might put 156 into TMR0
(256 - 100 = 156). However, since two instruction cycles are lost when you write to TMR0
(for internal logic synchronization), you should actually write 158 to the timer.

I am implementing a counter/clock, but the clock loses time or is
inaccurate.

; see if it was zero, if so,

; if not zero yet, keep waiting
