Watchdog: Incorrect Operation of CPU Watchdog When WDCLK Source is OSCCLKSRC2

Revision(s) Affected

0, A, B

Details

When OSCCLKSRC2 is used as the clock source for CPU watchdog, the watchdog may fail to generate a device reset intermittently.

Workaround(s)

WDCLK should be sourced only from OSCCLKSRC1 (INTOSC1). The CPU may be sourced from OSCCLKSRC2 or OSCCLKSRC1 (INTOSC1).
