X means that the value of these registers or bits is not influenced.
Remarks in brackets explain functional meaning.
Reading the command register will always reflect a binary ‘11111111’.
On bus-off the error interrupt is set, if enabled.
Internal read/write pointers of the RXFIFO are reset to their initial values. A subsequent read access to the RXB
would show undefined data values (parts of old messages). If a message is transmitted, this message is written in
parallel to the receive buffer but no receive interrupt is generated and the receive buffer area is not locked. So, even
if the receive buffer is empty, the last transmitted message may be read from the receive buffer until it is overridden
by the next received or transmitted message.
Upon a hardware reset, the RXFIFO pointers are reset to the physical RAM address ‘0’. Setting CR.0 by software or
due to the bus-off event will reset the RXFIFO pointers to the currently valid FIFO start address which is different
from the RAM address ‘0’ after the first release receive buffer command.

(CR)
The contents of the control register are used to change the behaviour of the CAN controller. Bits may be set or reset by
the attached microcontroller which uses the control register as a read/write memory.

microcontroller receives an overrun interrupt
signal (see also status register; Table 5)
disabled; the microcontroller receives no overrun
interrupt signal from the SJA1000

microcontroller receives an error interrupt signal
