Note: Priority level 0000
For interrupt requests which are to be serviced by the PEC, the associated PEC channel
number is derived from the respective ILVL (LSB) and GLVL (see figure below). So
programming a source to priority level 15 (ILVL=1111

group 3...0. The actual PEC channel number is then determined by the group priority
field GLVL.
Figure 8-5
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.
