Table 1-34. Reset Sources and Vector Locations
1.12.2 Interrupt Vectors
Table 1-35 lists all interrupt sources and vectors in the default order of priority. The interrupt module (see
Chapter 6, “Interrupt Module (S12SINTV1)”) provides an interrupt vector base register (IVBR) to relocate
the vectors.
