Watchdog Module (WDOG)
The Watchdog (WDOG) timer module protects against system failures by providing a method of escaping
from unexpected events or programming errors. Once the WDOG module is activated, it must be serviced
by software on a periodic basis. If servicing does not take place, the timer times out. Upon a time-out, the
WDOG Timer module either asserts the wdog signal or a system reset signal wdog_rst depending on
software configuration. The WDOG Timer module also generates a system reset via a software write to
the Watchdog Control Register (WCR), a detection of a clock monitor event, an external reset, an external
JTAG reset signal, or if a power-on-reset has occurred.

Signal Descriptions
This section:
Identifies and defines all device signals in text, tables, and (as appropriate) figures. Signals can be
organized by group, as applicable.
Contains pin-assignment/contact-connection diagrams, if the sequence of information in the data
sheet requires them to be included here. Otherwise, these figures appear in
Section 5, “Package
Information and Pinout.”

Functional Multiplexing
Table 4
shows functional multiplexing information. Functional multiplexing allows the user to select the
function of each pin by configuring the appropriate GPIO registers when those pins are multiplexed to
provide different functions.
