To use vectors specified in Table 3-2, the user must insert a jump extended opcode in the three
byte field of the vector required. For an example, for the IRQ vector, the following is performed:
1. Place $7E (JMP) at location $00EE.
2. Place IRQ service routine address at locations $00EF and $00F0.
The following is an example where the IRQ service routine starts at $0100:
$00EE
