After entering the interrupt service routine of a Reset or a P0.1 interrupt, the zero-bit Z
and the carry-bit C in the status register SR are not reset as expected.
The interrupt vectors and the associated interrupt vector addresses of the MSP430E325 device are shown
in Table 4–2 (or Table 4–3 for the MSP430E33x).
