23.14.2 Performing CAN Configuration
If the Reset bit in the CiCTLR register (i = 0, 1) is changed from “0” (operation mode) to “1” (reset/
initialization mode) in order to place the CAN module from CAN operation mode into CAN reset/initializa-
tion mode, always be sure to check that the State_Reset bit in the CiSTR register is set to “1” (reset mode).
Similarly, if the Reset bit is changed from “1” to “0” in order to place the CAN module from CAN reset/
initialization mode into CAN operation mode, always be sure to check that the State_Reset bit is set to “0”
(operation mode).
The procedure is described below.
To place CAN Module from CAN Operation Mode into CAN Reset/Initialization Mode
• Change the Reset bit from “0” to “1”.
• Check that the State_Reset bit is set to “1”.
To place CAN Module from CAN Reset/Initialization Mode into CAN Operation Mode
