Interrupt Sources And Vector Addresses - Panasonic MN101C00 User Manual

2-4-2 Interrupt Sources and Vector Addresses

In addition to reset, there are 20 interrupt vectors that indicate the starting
addresses of interrupt programs. These vectors are located in the 80-byte
ROM address area X'04004' to X'04053'.
