See UCB_DFlash in the User Manual, and PROCOND.RAMIN/RAMINSEL. With the default values, all of RAM is initialized on a warm power-on reset (i.e., your external watchdog asserts PORST).

It sounds like you want to set RAMIN to Init_Cold (2), so that RAM is only initialized on a cold power-on reset.

Also be aware of 4.1.3, RAM overwrite during start-up: the BootROM may alter the first 8K of DSPR.
