7.1 Watchdog Timer

The main difference between the two families lies in the fail-safe operation.

In the F2xx family, WDT is typically timed by ACLK, which is sourced by a crystal or the VLO. If crystal failure occurs, WDT defaults to MCLK. If MCLK is also sourced by a crystal, the DCO is automatically activated.

In the FR59xx family, the WDT fail-safe defaults to VLO instead of the DCO.
