About the MSPM0G3507 evaluation board，The WWDT reset is incorrect

Hi，team：

      I am debugging the MSPM0G3507 module，WWDT is initialized，If the system is normal when the reset operation is not performed, it will reset normally every 4 seconds。However, if the reset operation is added, the system will run away and the serial port will always print 0xFF。How to correct reset operation? thank you。In addition, when emulating with the emulator, even if the WWDT reset the system will not stop at the breakpoint, which is strange。
