Bit Symbol Bit Name Description R/W
15 to 0 CFID[15:0] Transmit/Receive FIFO Buffer
ID Data L
When CFM[1:0] value is B'01 (transmit mode):
Set standard ID or extended ID. For standard ID, write an ID
to bits 10 to 0 and write 0 to bits 15 to 11.
When CFM[1:0] value is B'00 (receive mode):
Standard ID or extended ID in the received message can be
read. For standard ID, read bits 10 to 0. Bits 15 to 11 are read
as 0.
R/W
Modify these bits only when the CFM[1:0] value in the CFCCHk register is B'01 (transmit mode). This register is
readable only when the CFM[1:0] value is B'00 (receive mode).
This register can be read/written when the RPAGE bit in the GRWCR register is 1.
• CFID[15:0] Bits
These bits indicate the ID of the received message stored in the transmit/receive FIFO buffer when the CFM
[1:0] value is B'00.
When the CFM [1:0] value is B'01, set the ID of the message to be transmitted from the transmit/receive FIFO
buffer.
