#173971 - Micro freeze
Hello,

I've got an electronic card built around a 80C552.

Sometimes the micro freeze and the only solution is to make a hard reset to relaunch the micro.

Yet, I've activated the watchdog.

The freeze is random (never or once a day, once a week...).

Thanks to help me because I don(t understant how the micro can freeze though the watchdog is activated.

Thanks.
