Interrupt Vector Addresses
The interrupt vectors and the power-up start address are located in the address range 0FFFFh to 0FF80h. The
vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence.

(1)
Multiple source flags
(2)
A reset is generated if the CPU tries to fetch instructions from within peripheral space or vacant memory space.
(Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general-interrupt enable cannot disable it.
(3)
Interrupt flags are located in the module.
(4)
Only on devices with ADC, otherwise reserved.
(5)
Reserved interrupt vectors at addresses are not used in this device and can be used for regular program code if necessary. To maintain
compatibility with other devices, it is recommended to reserve these locations.
