Hi,
In the data sheet of tm4c1294ncpdt it mention that first timeout only generate interrupt and second timeout will generate the reset.
Is it possible to generate reset in the first timeout itself.
Regards
Nikhil

Ni Nikhil,
No, it is not possible to generate reset in the first timeout.
14.2 Functional Description
The Watchdog Timer module generates the first time-out signal when the 32-bit counter reaches
the zero state after being enabled; enabling the counter also enables the watchdog timer interrupt.
The watchdog interrupt can be programmed to be a non-maskable interrupt (NMI) using the INTTYPE
bit in the WDTCTL register. After the first time-out event, the 32-bit counter is re-loaded with the
value of the Watchdog Timer Load (WDTLOAD) register, and the timer resumes counting down
from that value. Once the Watchdog Timer has been configured, the Watchdog Timer Lock
(WDTLOCK) register is written, which prevents the timer configuration from being inadvertently
altered by software.
If the timer counts down to its zero state again before the first time-out interrupt is cleared, and the
reset signal has been enabled by setting the RESEN bit in the WDTCTL register, the Watchdog timer
asserts its reset signal to the system. If the interrupt is cleared before the 32-bit counter reaches its
second time-out, the 32-bit counter is
