NOTES:
Dec 08, 2006
1. In EW0 mode, the interrupt vector table and interrupt routine for interrupts to be used should be allocated to the RAM area.
2. td(SR-SUS) is needed until the interrupt request is acknowledged after it is generated. The interrupt to enter suspend
3. When no interrupt is used, the instruction to enable interrupts is not needed.
