This register is writable only when the CFM[1:0] value in the RSCAN0CFCCk register is 01
(transmit mode). This register is readable only when the CFM[1:0] value is 00
RSCAN0CFIDk register should not be read or written when the CFM[1:0] value is 10
mode).
CFIDE Bit
This bit indicates the ID format (standard ID or extended ID) of the received message stored in the
transmit/receive FIFO buffer when the CFM[1:0] value is 00
bits are used to set the ID format of the message to be transmitted from the transmit/receive FIFO
buffer.

Set standard ID or extended ID. For standard ID, write an ID to bits b10 to
b0 and write 0 to bits b28 to b11.
Standard ID or extended ID in the received message can be read. For
standard ID, read bits b10 to b0. Bits b28 to b11 are read as 0.
