The watchdog module is the same as the one on previous TMS320C2000 devices, but with an optional lower limit on the time between software resets of the counter. This windowed countdown is disabled by default, so the watchdog is fully backwards-compatible.
The watchdog generates either a reset or an interrupt. It is clocked from the internal oscillator with a selectable frequency divider.
Figure 5-5 shows the various functional blocks within the watchdog module.
