19.5 Operational Modes
Figure 19.13 Transition between Operational Modes
The CAN module has the following four operational modes.
• CAN Reset/Initialization Mode
• CAN Operation Mode
• CAN Sleep Mode
• CAN Interface Sleep Mode
Figure 19.13 shows the Transition between Operational Modes.
19.5.1 CAN Reset/Initialization Mode
CAN reset/initialization mode is activated upon MCU reset or by setting the Reset bit in the C0CTLR
register to 1. If the Reset bit is set to 1, check that the State_Reset bit in the C0STR register is set to 1.
Entering CAN reset/initialization mode initiates the following functions by the module:
• CAN communication is impossible.
• When CAN reset/initialization mode is activated during an ongoing transmission in operation mode,
• Registers C0MCTLj (j = 0 to 15), C0STR, C0ICR, C0IDR, C0RECR, C0TECR, and C0TSR are initialized.
• Registers C0CTLR, C0CONR, C0GMR, C0LMAR, and C0LMBR, and the CAN0 message box retain
the module suspends the mode transition until completion of the transmission (successful, arbitration
loss, or error detection). Then, the State_Reset bit is set to 1, and CAN reset/initialization mode is
activated.
All these registers are locked to prevent CPU modification.
