The following sections describe the theory of operation of the software watchdog timer (WDT) in the
device, including a definition of the external signals and the functions they serve. Additionally, the
configuration, control, and status registers are also described. Note that individual chapters in this book
describe specific initialization aspects for each individual block.
5.4.1
The device provides a software watchdog timer (WDT) feature to prevent system lock in case the software
becomes trapped in loops with no controlled exit. Watchdog timer operations are configured in the system
watchdog control register (SWCRR).
The watchdog counter is a free-running down-counter that generates a reset or a non-maskable interrupt
on underflow. To prevent a reset, software must periodically restart the countdown. The WDT is
responsible for asserting a hardware reset or machine-check interrupt (mcp) if the software fails to service
