See section 19.2.2 of the C167CS user manual for information on the Bit-timing registers. (CS is used on the 2xCAN ESX. The CAN registers are identical to the 1xCAN ESX, though).
In the ESX BIOS, the function
init_can() automatically configures the Bit-timing register by calling the undocumented BIOS function
set_can_bittime_reg(). The setting to use is hardcoded and is chosen based on the bitrate and the clock frequency. The following BTR settings are used by the BIOS:
You can call
can_init() to set your own custom configuration.
|Bitrate (kbit/s)||20 MHz||40 MHz|
