6.9.7 Watchdog Timer (WDT_A)

The primary function of the WDT_A module is to perform a controlled system restart if a software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed in an application, the module can be configured as an interval timer and can generate interrupts at selected time intervals.

The watchdog can generate a reset on either a time-out or a password violation. This reset can be configured to generate either a Hard Reset or a Soft Reset into the system. See the WDT_A chapter in MSP432P4xx SimpleLink™ Microcontrollers Technical Reference Manual for more details.

Table 6-52 WDT_A Clocks

WDTSSEL NORMAL OPERATION
(WATCHDOG AND INTERVAL TIMER MODE)
00 SMCLK
01 ACLK
10 VLOCLK
11 BCLK

CAUTION

The WDT must be set to interval mode before transitioning into the LPM3 or LPM3.5 modes of operation. This allows the WDT event to wake the device and return it to active modes of operation. Using the WDT in watchdog mode may result in nondeterministic behavior due to the generated reset.
