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.

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.

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

SimpleLink™ Microcontrollers Technical Reference Manual

for more details. The WDT should typically be

configured to generate a Hard reset into the system. A Soft reset resets the CPU but leaves the rest of the
system and peripherals unaffected. As a result, if the WDT is configured to generate a Soft reset, the
application should assume responsibility for the fact that a Soft reset can corrupt an ongoing transaction
from the CPU into the system.

lists the clocks that can be selected as the source for the WDT_A module.

ADC14

The ADC14 module supports 14-bit analog-to-digital conversions up to 1 Msps sampling rate with
differential and single-ended inputs. The module implements a 14-bit SAR core, sample and hold circuit,
reference generator and a conversion result buffer. The window comparators with a lower and upper limit
allow CPU independent result monitoring through different window comparator interrupt flags.
