Reserved
The values read from this bit is indeterminate. Do not set this bit.
Overload Frame Flag
This status bit is set by the hardware as long as the produced overload frame
is sent.
This flag does not generate an interrupt
Reserved
The values read from this bit is indeterminate. Do not set this bit.
Transmitter Busy
This status bit is set by the hardware as long as the CAN transmitter
generates a frame (remote, data, overload or error frame) or an ack field. This
bit is also active during an InterFrame Spacing if a frame must be sent.
This flag does not generate an interrupt.
Receiver Busy
This status bit is set by the hardware as long as the CAN receiver acquires or
monitors a frame.
This flag does not generate an interrupt.
Enable On-chip CAN Controller Flag
Because an enable/disable command is not effective immediately, this status
bit gives the true state of a chosen mode.
This flag does not generate an interrupt.
Bus Off Mode

Error Passive Mode
