For different cores, why different watchdogs are required?

Jump to solution

Using single wdg at driver level and 2 wdgm instance at service layer level also can monitor both CPU0 and CPU1, right?

Then why different watchdogs are available in TC3XX family ? Is it due to any safety mechanism?

Whether using single wdg (CPU0WDG) can make any safety violation?

Hello,

In the TC3xx concept, the CPU watchdog is associated with the CPU, the watchdog configuration registers like WDTCPUyCON0 can be written by the specific CPU, CEy register is associated with a specific CPU watchdog.

Thanks.

Hello,
Is this query related to MCAL?
MCAL topics cannot be discussed in community.
