Field Descriptions

Bit Field Value Description

31-0 WWDSIZE 0 The DWWD window size

0000 0005h 100% (The functionality is the same as the standard time-out digital watchdog.)

0000 0050h 50%

0000 5000h 12.5%

0005 0000h 6.25%

Note: The DWWD window size can be selected by the application even when the DWWD

counter is already enabled. If a change to the WWDSIZE is made before the watchdog service

window is opened, then the change in the configuration takes effect immediately. If a change to

the WWDSIZE is made when the watchdog service window is already open, then the change in

configuration takes effect only after the watchdog is serviced.
