  * @brief CAN_Bal_2812 extended-CAN register space.

  * The wire layout is used by BALZAM Src/balzam_7/CanSetupBalzam7.c:
- * one big-endian address/mask word followed by three big-endian register words.
+ * eCAN MDL precedes MDH on the wire: value2, value3, address/mask, value1.
+ * Each word is big-endian; address/mask is at bytes 4..5, not 0..1.
+ * BA000x routes PM -> node; BA001x routes node -> PM.
+ * The MPU panel uses 745009 / 745019 with the same register layout.
