In the above figure, the high priority is the upper part of the red line, and the low priority is the lower part of the red line. If one of the interrupt sources is in both the upper and lower parts, it means that it can be set to either high priority or low priority. For example, TMR0 (timer 0) is in both the upper and lower parts; while INT0 (external interrupt 0) is only in the upper part and not in the lower part, which means that it can only be set to high priority and cannot be set to low priority. 21IC Basic Knowledge
