Simultaneous requests for PEC channels are prioritized according to the PEC channel
number, where channel 0 has lowest and channel 7 has highest priority.
Note: All sources that request PEC service must be programmed to different PEC
The table below shows in a few examples, which action is executed with a given
programming of an interrupt control register.
