36.2.29 Receive Buffer Register nBH (RMPTRn) (n = 0 to 15)
x: Don’t care
This register can be read when the GRWCR.RPAGE bit is 1.
RMPTR[11:0] Bits (Receive Buffer Label Data)
These bits indicate the label information of the message stored in the receive buffer.
RMDLC[3:0] Bits (Receive Buffer DLC Data)
These bits indicate the data length of the message stored in the receive buffer.
