Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range of 0FFFFh–0FFC0h.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
If the reset vector (located at address 0FFFEh) contains 0FFFFh (e.g., flash is not programmed), the CPU goes
into LPM4 immediately after power up.

(1)
A reset is generated if the CPU tries to fetch instructions from within the module register memory address range (0h–01FFh) or from
within unused address range.
(2)
Multiple source flags
(3)
(non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
Nonmaskable: neither the individual nor the general interrupt-enable bit disables an interrupt event.
(4)
Interrupt flags are located in the module.
(5)
This location is used as bootstrap loader security key (BSLSKEY). A 0AA55h at this location disables the BSL completely. A zero (0h)
disables the erasure of the flash if an invalid password is supplied.
(6)
The interrupt vectors at addresses 0FFDCh to 0FFC0h are not used in this device and can be used for regular program code if
necessary.
