Vector Table Area
The 1K–byte area 00000H to 003FFH in the memory space holds 256 vectors (4 bytes used per vector) for the start
addresses of interrupt routines initiated by interrupt requests, break instructions, etc.
In the initial state, vectors 0 to 47 are reserved as V55PI family dedicated on-chip peripheral and software interrupt
vectors. For vectors 8 to 47, the vector address of hardware interrupts except NMI can be changed by means of bits V0
and V1 of the interrupt mode control register (IMC).
