*
* Normal vector interrupts use a vector table with 16 entries (2 bytes
* per entry). Each entry holds the address of the interrupt handler.
*
* The vector table address is determined by 11-bits from the I and IL
* registers. The vector table must be aligned on 32-byte address
* boundaries.
* - Traps vector to logic address 0x0000 which may or may not be the same
* as the RST 0.
* - INT0
