If the WDT is not serviced before the timer overflow, a system malfunction is assumed.
As a result, the WDT NMI is triggered (assert FNMIWDT) and the reset prewarning is
entered. The prewarning period lasts for 30
(assert WDTRST).
The WDT has a “programmable window boundary” which disallows any refresh during
the WDT’s count-up. A refresh during this window boundary constitutes an invalid
access to the WDT, causing the reset prewarning to be entered but without triggering the
WDT NMI. The system will still be reset after the prewarning period is over. The window
boundary is from 0000
00
After being serviced, the WDT continues counting up from the value (<WDTREL> * 2
The time period for an overflow of the WDT is programmable in two ways:
•
•
The period,
by the following formula:
If the Window-Boundary Refresh feature of the WDT is enabled, the period
between servicing the WDT and the next overflow is shortened if WDTWINB is greater
than WDTREL, see
replacing WDTREL with WDTWINB. For this feature to be useful, WDTWINB cannot be
smaller than WDTREL.
