interrupt vector addresses
The interrupt vectors and the power-up starting address are located in the address range of 0FFFFh to 0FFE0h.
The vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence.

NOTES: 1. Multiple source flags
2. Interrupt flags are located in the module.
3. (Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt-enable cannot.
4. A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h to 01FFh) or
from within unused address ranges (from 0600h to 0BFFh).
