38.5.1 Power Management
The CAN continues to operate in idle0 Sleep mode, but cannot operate in idle2 and standby Sleep modes. Consequently, the CAN interrupts can only be used to wake up the device from idle0 Sleep mode. Refer to the Power Manager chapter for details on the different sleep modes.
The CAN module has its own Low-Power mode. The clock sources cannot be halted while the CAN is enabled unless this mode is used. Refer to the Sleep Mode Controller for additional information.
