CHAPTER 11 FCAN CONTROLLER
This is the CAN sleep mode control bit.
0: Normal operation mode
1: Switch to CAN sleep mode. Change in CAN bus performs wake-up.
Cautions 1. CAN sleep mode is canceled under the following conditions.
• When the CPU has cleared the SLEEP bit (to 0)
• When the CAN bus changes (only when CAN stop mode has not been
set)
2. The WAKE bit (see 11.10 (21) CAN1 definition register (C1DEF)) can be
set (to 1) only when CAN sleep mode is canceled by the change of the
CAN bus.
This is the initialization request bit used to initialize the CAN module.
0: Normal operation mode
1: Initialization mode
Cautions 1. Be sure to confirm that the CAN module has entered the initialization
mode using the ISTAT bit (ISTAT bit = 1) after setting the INIT bit (to 1).
When the ISTAT bit = 0, set the INIT bit (to 1) again.
2. If the INIT bit is set (to 1) when the CAN module is in the bus off status
(BOFF bit = 1), the CAN module enters initialization mode (ISTAT bit =
1) after returning from the bus off status (BOFF bit = 0).
