1.10 Vector Table

There is an interrupt vector table as the vector table. In the interrupt vector table, there are the fixed vector
table and the variable vector table.

1.10.1 Fixed Vector Table

The fixed vector table is an address-fixed vector table. The part of the interrupt vector table is allocated
to addresses 0FFDC
The interrupt vector table is comprised of four bytes per table. Each vector table must contain the
interrupt handler routine's entry address.
