CAN Module: Entering Configuration Mode

Hi,

 

I have another question related to the CAN module of the BF548.

 

Under which condition does the module enter the configuration

mode, once I have the the CCR bit in the control register?

I guess it waits for the current message on the CAN bus to complete,

if there is one.

 

Does it always enter the configuration mode, or is there a possibility

that it could wait forever (e.g. if there's a corrupt message) coming

in?

 

I'm asking this, because if there's a possibility for the module to wait

forever, I'd have to add a timeout. But if I don't know the conditions

for a successful entering the configuration mode, I can't set a sensible

timeout value.

 

Regards,

Gerhard
