12.1. Two Priority Levels
The bit values in the register IP and AUXIP determine what priority level each interrupt has. The following tables
show the bit values and priority levels associated with each combination.
Table: Priority Level Determined by [ IP ]
Table: Priority Level Determined by [ AUXIP ]
For example, if (IP.3)=(1), then Timer 1 has the priority level equal to 1, which is higher than level 0 with
(IP.3)=(0).
