After the supply voltage again exceeds the POR voltage threshold, the device progresses
through a full System Reset sequence as described in the POR section. Following POR,
the POR status bit in the Watchdog Timer Control Register (WDTCTL) is set to 1.

The VBO circuit can be either enabled or disabled during STOP mode. Operation during
STOP mode is set by the VBO_AO Option Bit. For information on configuring VBO_AO,

If the device is in NORMAL or HALT mode, WDT initiates a System Reset at time-out, if
the WDT_RES Option Bit is set to 1. This is the default (unprogrammed) setting of the
WDT_RES Option Bit. The
