Decompression unit
As every source is assigned a different interrupt vector, the source does not need to be identified in
the exception service routine. A priority level in a range from 0 to 15 can be set for each module
by interrupt priority registers 05 to 22 (IPR05 to IPR22). The on-chip peripheral module interrupt
exception handling sets the I3 to I0 bits in SR to the priority level of the accepted on-chip
peripheral module interrupt.
