6.4 Interrupt Vector Addresses

The interrupt vectors and the power-up starting address are in the address range of 0FFFFh to 0FFE0h (see Table 6-3). The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.

If the reset vector (at address 0FFFEh) contains 0FFFFh (for example, if 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 to 01FFh) or from within unused address range.
(2) Multiple source flags
(3) Interrupt flags are in the module.
(4) (Non)maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
