CAN Nominal Bit Time Configuration Register

Note:

The individual bytes in this multibyte register can be accessed with the following register names:
- CxNBTCFGT: Accesses the top byte NBTCFG[31:24]
- CxNBTCFGU: Accesses the upper byte NBTCFG[23:16]
- CxNBTCFGH: Accesses the high byte NBTCFG[15:8]
- CxNBTCFGL: Accesses the low byte NBTCFG[7:0]
This register can only be modified in Configuration mode (OPMOD[2:0] = 100).
