3.3.1 Vector Table Area
start addresses used when a branch is made as the result of RESET input or generation of an interrupt request. When context
switching is used by an interrupt, the number of the register bank to be switched to is stored here.

The 64-byte area from 00000H to 0003FH is reserved as the vector table area. The vector table area stores the program
Any portion not used as the vector table can be used as program memory or data memory.
16-bit values can be written to the vector table. Therefore, branches can only be made within the base area.
