How do I adjust the BTR register on the ESX?
Wed, 07/07/2010 - 14:31 — adminSee 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:
| Bitrate (kbit/s) | 20 MHz | 40 MHz |
|---|
