do you need a POR or simple looking for the possibility of doing a software reset?
If a WDT-Reset will do simply write to WDTCTL with an incorrect password (WDTPW); this will reset the device.
keep inmind that a PUC cause by WDT or FLASH password violation won't reset the timer interrupts configurations. So after a PUC, you should keep GIE clear until all is set up perperly again. If you set GIE, assuming that no interrupts have been configured (which is true after a POR), teh timers will start firing even if the rest of the applicaiton isn't initialized. Default values written as (x) are only set on power-on (POR) and not touced by an PUC.
