14.4.3 CAN Data Bit Time Configuration Register

Note:
  1. The individual bytes in this multibyte register can be accessed with the following register names:
    • CxDBTCFGT: Accesses the top byte DBTCFG[31:24].
    • CxDBTCFGU: Accesses the upper byte DBTCFG[23:16].
    • CxDBTCFG: Accesses the byte DBTCFG[31:0].
  2. This register can only be modified in Configuration mode (OPMOD[2:0] = 100).
