Function

XT2 crystal failures may not be properly detected by the oscillator fault circuitry

Description

The XT2OF flag should be set if the XT2 frequency falls below 30kHz. If there is no oscillation at all, the flag will still operate properly. However, 0-30kHz produces an undefined state on XT2OF. When this occurs, OFIFG will not be set.

Workaround

Do not depend on the fault detection circuitry to accurately detect all failures.
