(1) Vector table area
The 64-byte area 0000H to 003FH is reserved as a vector table area. The program start addresses for branch upon
reset or generation of each interrupt request are stored in the vector table area.
Of the 16-bit address, the lower 8 bits are stored at even addresses and the higher 8 bits are stored at odd addresses.
