Steve,
I don't understand. Why do you need to check for the pin to be low? After Rn has become 0 it will just keep decrementing and neither set nor clear the pin. To get 255 steps you must reload CTR and the registers though when CTR becomes zero. Otherwise you get 256 steps and either 0% or 100% is unreachable. Maarten |
