Description
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
See Figure 38
Error passive mode
See Figure 38
