Offset:
• SWRST: CAN Software Reset
0: No effect.
1: Resets the CAN.
A software reset triggered hardware reset of the CAN is performed. It resets all the registers (except the CAN_PMSR).
• CANEN: CAN Enable
0: No effect.
1: Enables the CAN.
This enables the CAN to transfer and receive data.
• CANDIS: CAN Disable
0: No effect.
1: Disables the CAN.
No data is received or transmitted.
In case a transfer is in progress, the transfer is finished before the CAN is disabled.
In case both CANEN and CANDIS are equal to one when the control register is written, the CAN is disabled.
• ABEN: Abort Request Activate
0: No effect.
1: Activates the CAN abort request.
• ABDIS: Abort Request Deactivate
0: No effect.
1: Deactivates the CAN abort request.
In case both ABEN and ABDIS are equal to one when the control register is written, the CAN abort request is deactivated.
