The content of the status register reflects the status of the SJA1000. The status register appears to the microcontroller
as a read only memory.

bus-off; the SJA1000 is not involved in bus
activities
bus-on; the SJA1000 is involved in bus activities
error; at least one of the error counters has
reached or exceeded the CPU warning limit
ok; both error counters are below the warning limit
transmit; the SJA1000 is transmitting a message
idle; no transmit message is in progress
receive; the SJA1000 is receiving a message
idle; no receive message is in progress
complete; the last requested transmission has
been successfully completed
incomplete; the previously requested transmission
is not yet completed
released; the CPU may write a message into the
transmit buffer
locked; the CPU cannot access the transmit
buffer; a message is waiting for transmission or is
already in process
overrun; a message was lost because there was
not enough space for that message in the RXFIFO
absent; no data overrun has occurred since the
last clear data overrun command was given
full; one or more messages are available in the
RXFIFO
empty; no message is available
