I am using MPC5604S controller. How can I do force reset of the internal watchdog ? Is there any provision to reset by providing some value to any particular registers of internal watchdog.

Hi,

Now it is clear. It is always good to explain what you are trying to achieve.

use mode entry module:

And simple do a mode transition to mode Reset.

by writing a key:

0x00005AF0;              //Reset Mode & Key
0x0000A50F;              //Reset Mode & Key

Thanks Peter. I used this method to reset and its working fine. I wanted to know is there any other provision to reset controller using watchdog itself other than the watchdog getting expired.

Hi,

If you want to force reset by internal watchdog the easiest way it to let watchdog expire.

Set the timeout to the desired value.

My intention is, If any error occurs I want to reset the controller immediately without waiting for the watchdog to expire. In Renesas controller we can reset by giving a particular value to the watchdog register. So I thought we also will have similar register in MPC watchdog to reset immediately without waiting for the watchdog to expire.
