FlexCAN Errata e2583 (K20F120)

Hi All

 

Early silicon (0M33Z) had a FlexCAN errata e2583 which requires the OSCERCLK source to be enabled in order for CAN to function properly.

 

Since I am presently working with CAN on a K20FX512VLQ12 (revision 3N96B) and this errata is no longer is reported the workaround was disabled. However then the problem starts exactly as described in e2583 - the CAN controller won't leave the low power state.

 

So the workaround has had to be left on.

 

Is this expected and has maybe the errata not been solved?

 

Regards

 

Mark
