### Clocks
The M_CAN needs two clocks. The first clock *hclk*
The M_CAN needs two clocks. The first clock *hclk* is used for the internal bus interface. Thesecond clock *cclk* is used for the CAN communication. It should be one of the following values:
clk = {20 MHz, 40 MHz, 80 MHz}
It is important, due to internal clock crossings, that *hclk* is always higher or equal to *cclk*.
## MRAM Config
The last device tree value configures the setup and layout of the MRAM (message RAM).
