CAN address
Identifier, remote transmission request bit and data length
code have the same meaning and location as described in
the transmit buffer but within the address range 20 to 29.
As illustrated in Fig.4 the RXFIFO has space for
64 message bytes in total. The number of messages that
can be stored in the FIFO at any particular moment
depends on the length of the individual messages. If there
is not enough space for a new message within the
RXFIFO, the CAN controller generates a data overrun
condition. A message which is partly written into the
RXFIFO, when the data overrun condition occurs, is
deleted. This situation is indicated to the microcontroller
via the status register and the data overrun interrupt, if
enabled and the frame was received without any errors
until the last but one bit of end of frame (RX message
becomes valid).
6.3.9
A
CCEPTANCE FILTER
With the help of the acceptance filter the CAN controller is
abletoallow passingof receivedmessages to theRXFIFO
only when the identifier bits of the received message are
equal to the predefined ones within the acceptance filter
registers. The acceptance filter is defined by the
acceptance code register (ACR; see Section 6.3.9.1) and
the acceptance mask register (AMR; see Section 6.3.9.2).
