3.2.17.2 DIAG_OSCCTRL_ClkSwitchDueToCFD - DEPRECATED
Returns the status of the OSCCTRL_CLOCK_SWITCH
| CAUTION | |
|---|---|
This function is deprecated in release
v1.2.0
A fault of the CFD circuitry does not lead to a single
point fault (SPF). It may lead to a latent failure.
Do not
execute this function to diagnose XOSC failures related to a
safe clock switch. The software safety mechanism cannot
report a failure of the hardware mechanism.
| |
This function verifies the XOSC switched to safe clock on CFD. This function will enable the oscillator and verifies the XOSC switched to the safe clock when CFD occur.
