Bit Symbol Bit Name Description R/W
15 to 8 CFDB1[7:0] Transmit/Receive FIFO Buffer Data
Byte 1
When CFM[1:0] value is B'01 (transmit mode):
Set the transmit/receive FIFO buffer data.
When CFM[1:0] value is B'00 (receive mode):
The message data stored in the transmit/receive
FIFO buffer can be read.
R/W
7 to 0 CFDB0[7:0] Transmit/Receive FIFO Buffer Data
Byte 0
R/W
Modify these bits only when the CFM[1:0] value in the CFCCHk register is B'01.
This register is readable only when the CFM[1:0] value is B'00. When the CFDLC [3:0] value in the CFPTRk register is
smaller than B'1000, data bytes for which no data is set are read as H'00.
This register can be read/written when the RPAGE bit in the GRWCR register is 1.
