R = Unrestricted read, -n = Value after reset. The C0RMS0 is cleared to 00h on all forms of reset, including the reset established by the CRST bit.
This SFR is not present on the DS80C411.

CAN 0 receive message stored register 1. The C0RMS1 bits indicate which message center (9–15)
has successfully received and stored the last incoming message. The content of the C0RMS1 register
is updated each time a new message is successfully received and stored. The contents of the C0RMS1
register are automatically cleared following each read of C0RMS1 by the microcontroller. A bit value 1
indicates that the assigned message center has successfully received and stored new data since the
last read of the C0RMS1 register. A bit value 0 indicates that no new message has been successfully
received and stored since the last read of the RMS1 register. No interrupts are asserted because of the
C0RMS1 settings. This register works fully independent of the status bits in the CAN status register and
the INTIN7–0 vector in the CAN interrupt register, as well as of the INTRQ bit in the CAN message con-
trol registers.
