Sridevi,
A watchdog reset should reset everything and you should see SOC and RM initialize. We do not have the number of watchdog resets available to be read as an SBData command, but you can read how many have occurred though the I2C bus. Please refer to page 11 of the document SLUA665. It can be downloaded from the TI website.The iSubclass will be 39H. The first word in the 32 word block of data will be the number of full resets and the second word is the number of watchdog resets that have occurred.
