Re: TouCAN too slow by 2X?

Hi Allan

you said:

I see Rick's reply but missed the question. 

If CAN is running at div 2, its unlikely to be anything with the EBDF
and clkout as that only effects the EBI interface. Its more likely to
be the IMB divider - see the UMCR register for details.

You're right, it was not EBDF, I had missed "HSPEED".

from the MPC565 User Manual:

"12.3 Clock Module
The clock module within the UIMB interface generates the IMB3 clock. The
IMB3 clock is the main timing reference used within the IMB3 modules."

"The IMB3 clock is generated based on the STOP and HSPEED bits in the
UIMB module configuration register (UMCR). If the STOP = 1, the IMB3
clock is not generated. If the STOP = 0 and the HSPEED = 0, the IMB3
clock"
